Before we move on to the list of the top-rated services for flight ticket reservation, we want to share a few more tips.

The Best Flight Booking Sites

Looking for the best flight booking site? First of all, remember that in some seasons, it is usually more difficult to find cheap airline tickets, namely:

• Summer season – the main vacation period
• Early fall
• Long-lasting holidays like Christmas
• Vacations in educational institutions

Also, it’s necessary to consider both types of airlines. There are two types of airlines:

1. Low-cost or discount airlines (e.g., Wizzair, Ryanair, SkyUp, or Pegasus) – they provide a minimum of service because their main goal is to provide a budget flight. Therefore, you will have to pay for additional services separately. You should book tickets for such flights as early as possible – 4-5 months before departure.
2. Regular flights (for example, KLM, SAS, LOT, or Turkish Airlines) – they are designed for a comfortable flight, so luggage, food, beverages, and seat selection are usually already included in the ticket price. You can choose a flight for any day.

If you are free to choose the days, mind that the busiest day is Tuesday (you can save up to 20%). The most expensive and most unfavorable day for finding cheap tickets is usually Sunday.

As a rule, flights with transfers are cheaper. You can also save money when you buy tickets in both directions at once.

Google Flights

Let’s go back to the 1990s. That is when ITA created the first flight search engine known as QPX. Over the years, the system evolved into a more powerful engine for travelers. The initial goal was to assist them with finding the lowest fares on the market. Today, the Google Flights service provides more flexible information on prices and routes than most of its rivals. It also helps to monitor current offers. Most people think Google Flights is a reliable and user-friendly search engine supported by the world’s giant corporation. They trust this brand. 

Travelers can use a set of filters to narrow down their options. For example, they can search for tickets based on the preferred departure time or airline alliance. With Google Flights, they can even track prices to see if they’re falling over time.

While some people prefer their favorite destinations over the price, others would rather consider worse service but cheaper options. It all depends on the budget and will. Those focused on cheap airfare rather than a particular destination (e.g., choosing Albania over Spain for vacation), Google Flights can help you out perfectly. Simply enter the desired price range without filling out the destination field on the website. If you do so, Google Flights will show you a map of airfares around the world that match your budget.

Let’s say, a person is planning a trip from Warsaw to London, for instance. They have no specific preferences in airlines (like they only want WizzAir, for instance). Moreover, they are not tied to a specific take-off date. In this case, Google will recommend alternative airports or travel dates that will significantly reduce flight costs. It can also provide forecasts of when airfare prices are likely to rise and by how much.

You can keep an eye in real-time on the selected flight price using this service. The fees may fluctuate, so it’s up to you to decide when exactly to make a purchase. You do not have to monitor price changes 24/7 as you’ll receive notifications from the service each time any modifications take place. Just check your Google Assistant and email.

Google automatically detects the nearest airport and offers to select a flight. No wonder many travelers consider this service the best website to book flights – after all, a world’s giant corporation guarantees full security of every deal.

Pros	Cons
Real-time chart displays any changes in the price to let you pick the cheapest moment to fly.The service will send you an email whenever the price of your flight goes up or down.It is easy to apply various filters as per your preferences and shortlist the options.	Because this search engine is so powerful and offers many options, it can be overwhelming for a novice traveler.

Kayak

This service has a so-called Hacker Fares feature that helps you combine one-way tickets from different airlines and make a more informed decision. It is one of the most popular flight search engines in Eastern Europe.

Although Kayak is often categorized as an online travel agent (OTA), it is actually a metasearch engine. This means that you can’t buy tickets through Kayak, and the service redirects you to the airline or OTA sites for booking. 

The system can boast the same advantages as major metasearch engines. For instance, this service offers price alerts and search filters to customize the process. One thing that makes Kayak so attractive to many travelers worldwide is the so-called Southwest flights.

To access this extra option at no charge, it is necessary to register a free service’s business account. You may upgrade at any time as paid subscriptions have so much more to offer. Users are also happy with such functions as Hacker Fares. This feature allows you to estimate the cost of one-way tickets on different airlines. These fares can be cheaper than booking round-trip tickets with a single airline.

Do not forget about the Fee Assistant feature. This one was created to assist customers with estimating baggage fees and other possible unexpected travel costs.

Pros	Cons
Hacker Fares for a more informed decision.Price alerts to keep an eye on airfare prices.Kayak offers the most value when your travel plans are very flexible.	This site may be less appealing if you have a specific flight in mind.

Trip.Com

Trip.com is part of the NASDAQ-listed Trip.com Group, and is one of the truly best flight search engines. This online travel agency, established in 2003, now has over 45,100,400 employees and over XNUMX million members. With this information in mind, it is now clear why Trip.com is considered one of the leading agencies in the industry.

Going on a trip, vacation, or business trip? With Trip.com, you can fully plan your itinerary and get great deals on airfare, hotel reservations, or rail tickets. Trip.com is easy to get in touch with as their website is available in 18 languages, including Russian, English, German, Spanish, French, Korean, Chinese, and Japanese.
With Trip.com, booking airline tickets and hotels is very easy and fast. The agency has built an incredible network that allows it to provide customers with over 2 million individual flight itineraries and offers over 1.4 million hotels in 200 countries and regions.

On Trip.com you can choose exactly what is right for your trip based on whether you prefer budget airlines or first class. A complicated itinerary or a direct flight? Customers can apply filters to their search or sort the results by the criteria that matters most to them. It’s possible to track flight status on their website or via a dedicated app. You can pay for your orders fast and conveniently using credit or debit cards (e.g., VISA or MasterCard).

No doubt, Trip.com is one of the world’s leading online travel agencies. It’s especially nice for users who are hungry for special offers, ‘hot’ promos, and other bonuses. You can apply discounts on various types of travel products and services. 

Pros	Cons
Offers flights, hotels, trains, car rentals, and tours in one platform.Well-designed app allows for seamless bookings and trip management.Support available in multiple languages for travelers globally.AI-driven suggestions for hotels, flights, and tours based on user preferences.	May include hidden fees or higher prices compared to booking directly.Refund and cancellation policies can be restrictive and vary by provider.Limited upfront details on provider-specific terms or policies.

Expedia

Expedia is another trusted best flight search engine. Its history dates back to the early 1990s. Thus, it is an old, well-known competitor of Google Flights. Back then, people did not have any other option to search for and reserve flight tickets. It almost excluded any competition for Expedia, but how does it stack up now?

It is an international travel agency that helps you search not only for tickets but also for travel packages and hotels. In addition, the service’s loyalty program helps you earn points for your next booking.

On the Expedia travel platform, you can book not only cheap airline tickets, but also everything you may need while traveling. For example, a hotel room, a rental car, a yacht cruise, tickets to events or venues, and even rent an apartment. At the same time, the site offers to buy all this in all-inclusive packages, with which you can save extra money. Thus, you can simultaneously book a cheap airline ticket, a room in the desired hotel, and a rental car for traveling around the place. 

One can reserve separately just a hotel and a car, for example – why not? Savings when booking a package can achieve up to 20-30%, which is very nice for long trips. Expedia also offers special prices for community members, gives travel tips, and has convenient mobile apps.

Expedia does not always come up with the best deals based on your search requests. Still, users do not spend more than they would on the official websites of various airlines. There are two sides to the coin. Expedia has something outstanding to offer: a generous rewards program. You can earn extra points and unlock savings. It will help you to cut costs on cruises, car rentals, accommodations, entertainment, and even vacation packages.

While you can earn miles for flights booked through Expedia, you often won’t be able to earn miles to qualify for tier status. You may also not be eligible for upgrades.

Pros	Cons
Expedia Rewards (although the earning potential is greater on hotels, cars, packages, events, and cruises than on flights).Easily finds and offers rather cheap tickets and reservations.	The number of miles you earn to reach elite status may be limited.Your ability to qualify for upgrades may be limited when booking through Expedia.

Hopper

It’s not just another service for finding cheap airfare. The new iOS app Hopper can tell you the best time to buy tickets for your trip. That is what makes this solution stand out from the rest of flight booking sites. Hopper analyzes millions of airline connections every day to predict changes in their prices as accurately as possible. 

The dedicated mobile software is straightforward and minimalistic. It does not distract users with dozens of useless options or shiny graphs. You can navigate through four equally useful sections: Dates, Prediction, Tips, and Flights. The journey begins once you enter your current location (or the place you would like to fly from). The app then will show you the nearest airports. Next, by selecting your departure and destination points, you will get detailed information to plan your perfect trip.

Two tabs help you find the optimal price: Dates and Prediction. The application offers a convenient calendar with dates in different colors for your comfort. The color depends on the airfare. The Prediction feature is there to disclose whether flight fees for the chosen destination may go up or decrease all of a sudden. Wish to keep an eye on your journey? The Watch This Trip function activates notifications to let you know whenever the lowest fee is on the horizon. 

You can download Hopper for free on the App Store. Make sure you have an iOS8 device so that you can both download and install the software. This app is a nice way to avoid high rates for trips, allowing you to save your funds for something better.

Pros	Cons
Allows users to monitor fare changes and secure deals with price alerts. Advanced search filters for flexible dates and budgets.Combines air, train, and bus travel into seamless itineraries (multi-modal options).	Limited direct airline support, meaning airlines may not assist directly with Kiwi-booked flights.Refunds and changes can be difficult, with complex terms and conditions.Additional service fees may apply for booking, changes, or customer service assistance.

Kiwi

While for some it is the best site to book flights, others call it one of the worst decisions, but they are in the minority. The platform promises everyone to find the perfect route according to their needs and budget. It has everything for a quick and convenient search – filters, a section with popular destinations, a section with promotions and bonuses. As a result, about 40 thousand air tickets are bought daily on the site.

If necessary, you can use the functions of buying and booking (with certain guarantees), solve the issue of hotel and car rental (through the services of partners), etc. The project is partly similar to Aviasales, which allow you to find the cheapest airline tickets, but there are many more useful features here. On the main page of the site, you can see a window for searching for tickets taking into account various trip’s parameters, such as your route, dates of stay in certain places, number of visitors (adults, children and infants), class of flight, etc.

The service has a native mobile application that gives you access to special offers and hidden functions. With its help, you can book tickets with one click, download boarding passes, and receive notifications about the trip.

In general, this site helps book airline tickets by combining routes of different airlines to create cost-effective plans.

Pros	Cons
Innovative tool known as Nomad feature for planning multi-city trips at the best prices. Offers itineraries that combine unique airlines that don’t normally partner.	Reports of slow or unhelpful responses to problems or disputes of their clients.Acts as a middleman, which can complicate booking changes or cancellations.

Priceline

Priceline is an online travel agency that developed an online booking platform to expand its customer base a lot. It can boast a wide network of credible partners who trust this company. This service is tailored to budget-conscious users. If you wish to cut your expenses as much as possible, this solution might be right for you. Priceline is generous for providing discounts for a wide range of travel-related purchases. Those could be vehicle rentals, accommodations, and different vacation packages. That’s why for some people it’s truly the best website for flights.

Thanks to its connections, Priceline automatically compares and updates rates for different directions. This service possesses a truly friendly user interface, ensuring you check out the ‘hottest’ deals hassle-free. Over the years, Priceline has evolved to include innovative booking options that appeal to a wide range of travelers. While some of its customers plan everything ahead, others always postpone everything to the last minute, hoping that Priceline will lend a helping hand. 

Two features that make Priceline stand out for sure are Pricebreakers and Express Deals. Not so many rivals can offer discounts that high in exchange for flexibility and loyalty. With the help of their native application, users easily manage or cancel their reservations, contact customer support within minutes. The best thing is that travelers can take advantage of last-minute deals – all from the convenience of their device.

The comprehensive search is possible thanks to the company’s excellent relations with many providers worldwide. Priceline brings together offers from a variety of suppliers to provide users with a wide range of options tailored to their travel needs and budget constraints. 

Pros	Cons
Competitive prices on a wide range of accommodations. Express Deal feature to book at discounted rates.Earn VIP points to redeem for various travel-related expenses.	Limited flexibility when it comes to editing or canceling reservations.Lack of transparency when it comes to knowing specific details before booking.

Hotwire

Hotwire is a comprehensive travel platform popular among travelers from different corners of the world. It is another candidate from our list to be called the best flight website. Interestingly, this service is a part of Expedia discussed earlier in this article. Thus, it has more limited functionality but still has something curious to offer. Among all, Hotwire regularly proposes significant discounts on car rentals, accommodations, and tour packages. 

By leveraging relationships with major travel suppliers, Hotwire is able to provide travelers with access to a wide range of travel options. Their loyal partners make it the way that customers get access to fees much lower than standard. The platform is particularly known for its Hot Rate offers. The only thing to keep in mind is that the website reveals the details of the resort or rental once the booking is confirmed. This unique approach allows Hotwire to negotiate lower prices with its partners. Plus, Hotwire works as a one-stop shop for travelers looking for affordable travel options without compromising on quality. 

The main function of the platform is to provide users with travel services at significant discounts, including accommodation, airline tickets, car rentals and travel packages. A distinctive feature of Hotwire is its Hot Fares deals, which hide information about the service provider until the booking is finalized, allowing the platform to offer lower prices. 

The platform caters to both last-minute travelers and those who plan their trips in advance, offering a flexible and user-friendly interface for all types of travel planning.

Pros	Cons
Package deals that include accommodation can save you money.24 hour cancellation policy.Lowest price guarantee.	Hotwire can sometimes charge booking fees.Hot Fares don’t always offer huge savings.

CheapOAir

CheapOair.com is one of the most popular travel sites in the world with the best airfares. The website helps to find exclusive flights at affordable prices and provides valuable advice during the search. Tourists and business travelers will both benefit from selecting accommodations, vehicle rentals, and excursions with this provider. Of course, relatively cheap flight tickets are of the main interest for their clients. The company has offices in New York, Toronto, London, and New Delhi. Correspondingly, their primary support is in English. There is a 24-hour client support service that consists of highly responsive experts. They typically respond within a minute.

Wish to save time, money, and nerves? CheapOAir speaks for itself as it does its best to offer the most affordable market prices after comparing partners’ rates. They consider rivals as well. The site’s interface may seem a bit overloaded, but it is done in the Western manner. Still, CheapOair provides all the travel information you need to make the best booking decisions. Those who choose this site have an opportunity to transfer their funds via trusted methods like American Express, Carte Blanche, Discover, MasterCard, Diners Club, and debit/credit cards. 

It’s easy to get started at CheapOAir: just enter the type of flight, city and date you want to fly to, then keep an eye on your flight. The team then compares all the flights on offer to bring you the best deals and booking options. When the price drops, you’ll get a notification and you can buy airfare right from the app. 

Pros	Cons
Helps find competitive rates by comparing options across multiple airlines and providers.Offers flights, hotels, car rentals, and vacation packages in one platform.Earn points through the ClubMiles loyalty program for future massive discounts.	Aggressive upselling, meaning it pushes extra insurance, seat upgrades, and add-ons during checkout.Travelers may face difficulty managing bookings directly with airlines as they possess limited control.

Skyscanner

Maybe, Skyscanner is not the best site for flights, but it has its significant advantages. Thanks to the Everywhere feature, users can find many more flights that are available worldwide.

Skyscanner specializes in finding the cheapest airline tickets and promises to buy them without any of its own “markups.” You will have to pay exactly the amount indicated on the website. No hidden costs.

The developers claim that they cooperate with more than 1100 travel agencies and constantly monitor prices. If the cost of tickets becomes unfavorable for the buyer, this company is removed from the search results. The ability to “mix” flights from different travel agencies allows you to save money on long-distance flights with transfers. Another feature is the ability to easily book a hotel, car, and everything you need for work and leisure. You can also choose different types of accommodation. The service offers technical support 7 days a week and in 30 languages. Overall, it is a reliable and modern service with a good reputation.

Pros	Cons
Flexible search.Easy to change language and currency.Price alerts.	There is little that makes this service unique. All the features offered are available on other websites.

Price Comparisons

There’s no secret that most people choose the best airfare sites based on the fees they set. Of course, when buying an air ticket on the Internet, you need to be sure that it is safe and you won’t lose your money by falling victim to fraudsters or any technical failures. However, the latter happens rarely, and it is usually possible to solve the issue.

The Internet offers even more opportunities to save money. On the aggregator’s website, you can select the specific day of the week. Most experts agree that it is cheapest to fly on Tuesday, Wednesday, and Saturday, especially when you manage to get tickets from 8 to 12 and from 14 to 18 hours. On weekends, the price does not change much throughout the day. Anyway, as each site analyzed in this post has its own fees, we suggest that you compare and contrast them before making the final choice.

Service	Lowest cost flight (with taxes & fees)
Google Flights	$398 (American/Delta)
Kayak	$438 (Delta)
Trip.com	$438 (Delta)
Expedia	$401 (American/Delta)

Finding a flight could seem like an insurmountable task. Time, date, cost, fare class, airline, and many other variables all have a role. Where can you get the most affordable flights, even when you have a clear idea of when and where you want to go? What are the best airline ticket sites?

If you are looking for consistently affordable airfare, there is no one-stop-shop for that. The majority of OTAs have prices that are very close to one another. You can see it from our review.

In any case, reserving and buying tickets online is always more cost-efficient and time-saving!
