Tips on booking cheap flights.

Looking for the best time to buy airline tickets to get a cheap flight to everywhere? We’ve got you covered anytime, anywhere. Here’s how to find the best deal for flight booking no matter where you want to go in the world.

Which day of the week is the best day to buy cheap airline tickets?

For both U.S. domestic and international travel, Sundays can be cheaper for airline ticket purchases. Fridays tend to be the most expensive day to book a flight. Booking on the right day of the week could save you up to 6% on your airfare, according to historical data*.

When is the best time to buy airline tickets?

Based on 2020 And 2021 global flight data for Economy tickets, prices usually start to increase 56 days before departure for domestic flights. When traveling internationally, prices usually start to increase 21 days before departure*. Keep in mind that this isn’t a hard-and-fast rule; keeping an eye on prices is a good idea when trying to find the best airfare deals. Compare fares across different airlines, and set up a price alert for your preferred route.

Which are the cheapest days to fly?

Analysis of domestic and international airfare prices shows that flying out on Fridays can be cheaper. Many travelers start their trips on Sundays, so your chances of a lower price are better when departing early in the week instead. Starting your trip on a Friday could be almost 11% cheaper than air travel on Sundays, so book flights online wisely*!

Which is the cheapest month to fly?

The cheapest month to fly can vary depending on where you’re going, so finding the best rates largely comes down to avoiding peak travel times for your destination. If you’re looking for cheap international flights , the most expensive month tends to be February, while the cheapest is November with cheap flights in November offering potential savings of up to 34.6% relative to February. Cheap domestic flights work a bit differently, with March being the most expensive and August being the least expensive with cheap flights in August offering savings of up to 35%*.

How can I get cheap last-minute flight deals?

The historical data analysis of flight pricing patterns shows that you can still find amazing airfare deals 3 weeks prior to departure* when traveling domestically. International last-minute flights offer great deals 2 weeks prior to departure if you’re flying premium, but economy travelers may want to strive for no less than 4 weeks out*.

What should I look out for when booking flights?

Several factors go into any flight booking, and you’ll need to keep an eye out for them all to ensure that you get the travel time, luggage policy, airline, and class you want. Consider which airport is closest to your ultimate destination (travelers to Los Angeles may prefer flights to LAX over flights to PSP , and make sure that the flight will accommodate all the luggage you plan on bringing.

Flights to Las Vegas tend to be pretty affordable as well. While the Vegas airport isn’t a hub for any major airline, it does have plenty of competition to keep prices relatively low.

Where can I fly for cheap?

Staying within a strict budget still allows you to find plenty of cheap flights, even to destinations like Puerto Rico. In fact, flights to Puerto Rico don’t even require U.S. citizens to have a passport. Flights to Alberta and other destinations in Canada can be fairly affordable as well.

Is it cheaper to buy flights last minute?

Flight tickets can be cheaper at the last minute depending on how late you’re actually booking, where you’re going, and the kind of flight you opt for. For domestic flights with Economy tickets, prices usually start to increase 3 weeks before departure, and 4 weeks for international flights, according to historical data*.

Are fully refundable flights available?

Frequently asked questions

What do i need to know before booking a flight.

There are various factors to consider when booking a flight including cost, fare classes, baggage policies, the complications of flying long haul, and complying with airport regulations. To make your booking journey smoother KAYAK has developed a comprehensive flight guide including insights on finding affordable flights, packing efficiently, and utilizing the best travel tools.

Which month of the year are flight prices lowest?

It’s well established that flights in the low season are generally cheaper than ticket prices during the high season. That means that knowing which month to find the lowest priced plane tickets will depend heavily on seasonality and your destination. While avoiding peak travel times can help you keep costs down, our data shows that the month with the lowest priced plane tickets for domestic flights based on all searches made on KAYAK in the last 12 months was January, while the most expensive was March. If you’re booking an international flight, then January is the cheapest month to fly and June the most expensive.

Can flying international flights with a layover save money on airfare?

For many long-haul international flights, flying non-stop is not possible and you will have to fly with a layover. Some routes will offer both and you could consider flying with a layover for a number of reasons. Firstly, breaking up what would otherwise be a long-haul flight, taking a rest and then completing the journey might make the flight more manageable. Secondly, prices can also be lower than non-stop flights, so while it might take longer for you to reach your destination, you could save money. We’ve looked at prices over the last 12 months for the 100 most popular international destinations for KAYAK users and on average, prices for non-stop flights were cheaper than flights with a layover.

How do I find the best flight deals on KAYAK?

A simple flight search at https://www.kayak.com/flights scans for prices on hundreds of travel sites in seconds. We gather flight deals from across the web and put them in one place. Then on the search results page you can use various filters to compare options for the same flight and easily choose the best flight deal from all of the deals coming straight from the travel sites to your screen, with no extra fee from KAYAK.

Does KAYAK query more flight providers than competitors?

Yes, KAYAK has access to more data and information than online travel agencies and consistently outperforms the competition in accuracy, globally.

What is KAYAK's "flexible dates" feature and why should I care?

Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you flights up to 3 days before/after your preferred dates. That way, you can see if leaving a day or two earlier will find you a better deal. You can also select the flexible "weekend" or "month" search options to widen your search range and find the cheapest price that works for you.

What is the cheapest day of the week to book a flight?

The best day to book your flight depends on a number of factors, but there are general trends that you can follow to increase your chances of cheaper plane tickets. Based on an analysis of KAYAK data for all flights departing from inside United States over the last 12 months, the cheapest day to fly for domestic flights is Wednesday. For international flights, Tuesday had the cheapest tickets on average.

When is the best time to buy plane tickets - Last minute or in advance?

Last minute flight deals are definitely up for grabs but when exactly to purchase your plane tickets will depend on where you’re traveling to and from. Based on all data for flight searches made on KAYAK over the last 12 months, prices for domestic flights remained below the average price up to 1 weeks before departure. For international flights, deals could still be had up to 1 weeks prior to the departure date, with prices remaining below average. If you’re flexible, KAYAK brings you both advance and last minute one-way and round-trip flight deals.

How does KAYAK find such low flight prices?

KAYAK processes over 2 billion flight queries annually and displays results from hundreds of airlines and third party sites, allowing it to find a variety of flight prices and options. It also displays results from 2M+ properties along with rental cars, vacation packages, activities and millions of verified reviews so users can see as many available travel options as possible.

How can Hacker Fares save me money?

Hacker Fares allow you to combine one-way tickets on different airlines when it can save you money over a traditional round-trip ticket.

How does KAYAK's flight Price Forecast tool help me choose the right time to buy?
