Couple checking detail before booking their flight

While most airlines list flights almost a year in advance, it’s not always best to book too soon. However, if you’re using airline points or flying over the holidays, the early bird gets the worm on the best tickets. Read on to learn when airlines release their flights, plus, how you can use KAYAK tools to know exactly when to book.

You can book most flights almost a year ahead.

  • The majority of the world’s airlines release tickets for purchase just under a year in advance.
  • Low-cost airlines, like Ryanair in Europe, can have a shorter booking window, from 6 – 9 months in advance.

But booking that far ahead doesn’t necessarily mean you’re saving money or getting the best deal. Plus, flight logistics like departure and arrival times often end up changing if you book further out.

How far in advance can you book domestic flights?

Most U.S.-based carriers allow booking cash tickets up to 11 months in advance. When it comes to award travel, some carriers will have different rules (more on that below). Here’s a list of 10 popular domestic airlines (alphabetically listed) and their usual timings:

AirlineAdvance booking time
Alaska Airlines331 days in advance
Allegiant Air6-9 months in advance
American Airlines331 days in advance
Delta Air Lines331 days in advance
Frontier330 days in advance
Hawaiian Airlines330 days in advance
JetBlue331 days in advance
Southwest Airlines6-8 months in advance.
Spirit330 days in advance
United Airlines330 days in advance

How far in advance can you book international flights?

For international travel, timing can vary by carrier. European low-cost airlines like Ryanair often release tickets 6-9 months in advance, but easyJet does release some flights up to 11 months in advance.

Full-service carriers such as Emirates, Qatar Airways, British Airways, Lufthansa, Air France and Virgin typically allow bookings up to 11-12 months ahead.

Long-haul flights may see the best fares 2-6 months before departure, though peak travel periods, like summer holidays, Christmas and Lunar New Year, usually require earlier planning. Flexibility in dates and monitoring fare trends on KAYAK can help secure the most competitive international prices.

When to book if you’re using airline points.

When it comes to award travel, the rules are straightforward: book as soon as possible. Award travel usually opens around the same time as the booking times for cash, so you can take the plunge without delaying.

Airlines don’t have as many award tickets for every flight, so booking early means you’re more likely to get the dates, seats and class of service that you’re after.

So, is there really a best time to book?

As a travel writer, I often get asked if there’s a “best time to travel,” as people want to know if there’s a secret hack to getting flights for the best prices. In reality, it depends. Just because a flight is available, it doesn’t necessarily mean you should book it straight away.

Popular destinations and peak season travel (Thanksgiving, for example) should generally prompt anyone to book earlier than usual. These flight schedules probably won’t change, and the closer you get to the travel time, the higher prices are likely to get.

Want to know when to book a specific trip? KAYAK’s Best Time to Travel tool uses your origin, destination and length of trip to determine when you should travel and when to book for the best price.

I wish I could be more of a spontaneous flier, but for me, I have found that three months ahead typically does the trick.

Most airlines release their flight schedules around 11 months in advance. With international travel, there are some rules worth following – summer months are very busy and you might not be able to get the exact flights you are after.

A good rule of thumb is to start looking roughly 6 months before your specific travel dates, and not wait much later than 3 months before you’re planning to get into the skies. A good idea is to check their websites, keep track of their social media, and see what information they are offering up about any upcoming deals.
