3 Best Sites to Compare Flight Prices

Google Flights is the best site to compare flight prices, with Skyscanner as the next choice and Kayak as another reliable option. Google Flights has flexible date searches, price trend analysis, and alerts when fares drop. Users rate it highly for researching routes and finding useful fare changes.

Skyscanner can help you find cheap flights through its wide range of filters and fast deal searches. Kayak also compares fares across options and includes fare alerts and filtering tools. All three sites work well for research before you book.

After you find a fare, book directly with the airline when possible. Direct booking makes delays and cancellations easier to handle because you deal with the airline instead of a third party. Users warn that online travel agencies can create problems with cancellations and changes, especially on complex itineraries.

Try flexible travel dates and nearby airports when you search. A traveler in Indiana, for example, can check Indianapolis as well as both Chicago airports. Price tracking can also send alerts when a fare drops and may provide price predictions.

Check one way tickets as well as round trips, since separate tickets can sometimes cost less. Search budget airlines separately too, because airlines such as Southwest might not appear on major comparison sites. After you find a low third party fare, you can call the airline, share the fare details, and ask whether it will match the price.

Best Comparison Sites

Google Flights is the top choice for comparing flight prices. Users praise its comprehensive features, including flexible date options, price trend analysis, and alerts for price drops. "Google Flights is S tier"
Skyscanner is another popular option for finding cheap flights. It is known for its extensive filtering options and ability to quickly identify good deals. "Skyscanner app"
Kayak offers a reliable and comprehensive comparison experience. It provides fare alerts and various filtering options, similar to Google Flights and Skyscanner. "Kayak: A reliable and comprehensive site for comparing flights, offering fare alerts and a variety of filtering options."

Why Book Directly with Airlines

Direct booking provides better support for delays and cancellations. Dealing with the airline directly is much simpler if issues arise, as third-party sites can complicate the resolution process. "If your flights are canceled or delayed, it's better to deal with the airline than a third party."
Avoid potential issues with third-party online travel agencies (OTAs). Some Users have experienced difficulties with cancellations or changes when booking through OTAs, especially with complex itineraries. "Do not be tempted by the super cheap prices shown by Kiwi or other third party online travel agencies. Ten out of ten times you will be ripped off."
Airlines often match third-party prices. After finding a good deal on a comparison site, you can sometimes call the airline directly and ask them to match the price, allowing you to book directly. "Then call the airline that has the best price, tell them what you found and on what site. Usually if they can verify it’s a valid third party offer, they will match it."

Tips for Finding Cheaper Flights

Be flexible with travel dates and airports. Adjusting your travel dates by a few days or checking nearby airports can lead to significant savings. "For example, if you are in Indiana, check Indianapolis airport but also both Chicago airports."
Utilize price alerts and tracking features. Many comparison sites, especially Google Flights, allow you to set up alerts that notify you when prices drop for your desired route. "You can also have it send you an alert when the price drops and it will give predictions."
Check one-way tickets and budget airlines separately. Sometimes booking two one-way tickets can be cheaper than a round trip, and budget airlines like Southwest might not appear on major comparison sites. "I travel extensively and sometimes will find the cheapest routes by searching one way for each ticket."

I’m on a quest to finding cheap flights. Have normally always used google flights to finding the cheapest. Is there someone else you guys use to find cheap flights?

Directly from the airline

Do not be tempted by the super cheap prices shown by Kiwi or other third party online travel agencies. Ten out of ten times you will be ripped off. As others have said, use Google flights for your research and then book directly with the airline.

About 60 days prior to departure begin checking the third party sites for deals. Make sure you read all the fine print regarding the booking, like restrictions, prepay no cancel etc. Then call the airline that has the best price, tell them what you found and on what site. Usually if they can verify it’s a valid third party offer, they will match it. They would rather you book direct with them because they don’t pay commissions on direct bookings.

Buying directly from the airline is always the best way to book. Using third-party sites just means problems... especially if there are delays or cancellations related to weather, which commonly happens in the Midwest around Christmas break.

Go on Google Flights and figure out which flights are cheap. Then buy the ticket on the airline's official website.

Christmas can be expensive... in order to try to save money, be flexible with your travel dates, and also check nearby airports on both ends, to see if there are cheaper flights using an alternative airport. For example, if you are in Indiana, check Indianapolis airport but also both Chicago airports. Same on the West Coast side of things.

Safe travels!

Use Google flights to find what you're looking for, then go to the airline's site to purchase. If your flights are canceled or delayed, it's better to deal with the airline than a third party.

I travel extensively and sometimes will find the cheapest routes by searching one way for each ticket. Other times, the round trip is cheaper. You just have to go to Google Flights and play around with it. You can also have it send you an alert when the price drops and it will give predictions.

10th comment saying directly from the airline, no other way.

Also, there is no magic trick to find an amazing deal. All of that bs about "second tuesday of the month, 3 months ahead, while its raining and your pc is freshly formatted and in incognito" doesn't work.

You can use Google Flights to see average prices, set a reallistic budget you're comfortable with, and buy them whenever they go down to that prize. I will emphasize realistic budget, if the average price is 500, don't expect them to go for 50.

I’ve used Google Flights before but it only tracks the specific flight or the day.

I’m flexible on the day and the airline and the times. Just want the cheapest around a particular week but could be any airline and could have a stop or nonstop or earlier by a couple of days or later by a couple too.

Is there an app or a website where I can just put destination and origin and it alerts me whenever around that time any airline and any flight has a good price?

I will be traveling (on a plane) for the first time alone next year. (In the past I've always gone with a group of people and someone else purchased the tickets for me.) Which travel site is the simplest/easiest to buy plane tickets online?

I was looking at kayak, but please let me know if you have any specific recommendations. I have two diff credit cards but I have never purchased plane tickets online before. ( I would just be purchasing airfare for one person, round-trip and nonstop if possible. I am most focused on finding the best deal as well as reliability/security of the website and something that's easy to use). Any advice/recommendations are greatly appreciated. Thank you.

Normally when I'm booking flights, I check Google Flights and Skyscanner to get the best deals but, like any sensible person, I book directly with the airline. But, at the moment, when I use both sites, flights through third parties are topping the listings by being a few hundred dollars cheaper.

If you know of a site that only includes the price direct from the airlines and not third parties, I'd really love if you could hook me up.

Google flights might be the best website with the worst marketing because there’s so many posts per day with people oblivious about its existence

  • Google Flights: Great for discovering the best travel dates and showing price trends across months. You can also set up alerts for price drops.
  • Skyscanner: Known for finding cheap flights quickly and has extensive filtering options.
  • Kayak: A reliable and comprehensive site for comparing flights, offering fare alerts and a variety of filtering options.
  • Momondo: Offers detailed price tracking and allows you to mix and match airlines to find the cheapest fares

I always go to the airlines and search. I would never use a third party site. If you have to reschedule that is just about impossible with third party companies. The fine print may say 30 days or 10 days notice required. I had a problem when I tried booking.com for a hotel room and booking.com was a nightmare but I called the hotel and told them the problem and they changed the dates no problem. I had to cancel my card and get a new one because booking.com wouldn’t allow me to change dates or cancel. I was trying all of this within 24 hour’s of booking my room. The room I initially booked was I believe 7 days before I needed the reservation. I have had a problem with one of the airlines before so I never ever use third party. If everything goes as planned you will never know if a third party stands up to the promises they have on their website. It’s when you have a trip planned with a friend and they tell you they are unable to go for whatever reason and it’s typically something that can’t be helped so your not upset with your friends. My husband and I have needed to change flights and have not had a problem with the airline directly as well as hotels as long as there’s 7 to 30 days and I am rescheduling. So be careful.

Yes! Use Kiwi (either the app or website). They have exactly what you're looking for and even more hacks - I use their Anywhere, Anytime feature as a hobby.

I usually use sites like kayak, Expedia or TripAdvisor to find reviews and pricing. But I usually book directly on the website. Same thing for flights. I check google flights for comparison and then book directly with the airlines

Google flights but remember the airline is not responsible for what they show. I found a great deal several times but price didn't match. Also check booking on a partner website to see if better deal.

What is everyone's preferred method for ensuring they are getting the best rates for flights?

Google's Flights interface is helpful, but that's all I really rely on

Extra Info/context:
The cards I use (My Citi Strata Premier is my main travel card) thankfully permit me to book flights through any portal. With American Airlines being a new transfer partner, I've been booking through their page.

- Skyscanner is another popular option for finding cheap flights. It is known for its extensive filtering options and ability to quickly identify good deals.
- Kayak offers a reliable and comprehensive comparison experience. It provides fare alerts and various filtering options, similar to Google Flights and Skyscanner.
