The Best Time to Book a Flight for Domestic, International, and Summer Travel

Buying plane tickets is something of an art form. Ideally, you want to secure your spot in advance to avoid the inevitable price spike as your travel dates get closer. Industry data reveals the sweet spot for booking domestic flights is 28 days, or 60 days for international flights. That said, the trends are always changing, and experts recommend booking earlier for peak travel periods like summer and the holiday season.

Flights generally open for booking about a year ahead of time, and the airfare will change often between then and takeoff. Although you can book just a couple of weeks before the departure date in some cases, prices are likely to be astronomical. In other cases, when you want to go somewhere popular or during a big travel weekend, flights could fill up faster than normal. Our advice: Track flight prices on Google Flights or Hopper as early as possible so you can keep an eye on cost fluctuations. Read on for more advice about when to book flights from the pros.

When to Book Flights for Domestic Travel

According to Expedia’s 2024 Air Travel Hacks report, you should aim to book 28 days before your domestic flight. “Doing so can save travelers up to 24 percent compared to those who wait until the last minute, from zero to six days out,” Expedia travel expert Christie Hudson tells Travel + Leisure.

For domestic trips, pricing is elevated when tickets are first released, about a year before the flight. Those prices will slowly creep downward, all the way to their lowest point in the prime booking window, after which you’ll likely see a huge increase in cost for last-minute travel.

When to Book Flights for International Travel

You’re better off booking earlier rather than later for international travel, but the Expedia report says ideally no more than four months before your desired departure date. The sweet spot is around 60 days. “This is a big change from 2022 data, which showed the cheapest fares were secured when travelers booked four to six months out.” Hudson says. “2023 data revealed that people who booked that far in advance actually paid more on average.” The report says the least expensive day of the week to book is Sunday and the most expensive is Friday, for both domestic and international travel.

The real trick to finding good deals on international airfare is to avoid booking your travel for peak times, which include summer and major holidays (don’t forget — that includes holidays in your destination, too).

When to Book Flights for Holiday 2024 Travel

Around the winter holidays is the priciest time to travel, says Katy Nastro, travel expert at Going. “Your best bet is to remember the Goldilocks zones: look to book between three to seven months ahead for domestic travel and four to 10 months ahead for international travel.”

Hudson advises that at the very latest, your holiday travel should be booked by mid-October. “But the biggest holiday travel savings actually come from choosing the right dates,” she says. “Avoiding the busiest days like the Wednesday before Thanksgiving and the Friday and Saturday before Christmas will yield major savings.”

Track flights and book your holiday tickets as soon as you find a decent deal, but make sure to book a fare that will give you a credit if you cancel (generally speaking, that means don’t book basic economy). That way, if prices drop between the time of booking and your travel dates, you can cancel your original ticket and use the credit to book the cheaper fare. The only downside is you’ll still have some remaining credit, but you can then use it to treat yourself to a future flight. Just don’t let that credit expire.

When to Book Flights for Summer 2025 Travel

Summer is traditionally one of the most popular times of the year to travel, which means it can be tough to find a good deal on airfare. Ideally, you should book flights for summer travel as soon as possible, preferably at least six months in advance.

“The best time to book for peak season is … the opposite season,” Nastro says. “While most of us are scrambling to focus on our winter holiday plans, we should also keep our eyes open for some great summer fares.”

She notes that the booking window for peak season ranges between three and seven months for domestic flights and four to 10 months for international trips. “And if you do book something, keep that flight alert on,” says Nastro. “If it drops again, depending on your ticket type, you can call to rebook and get a refund or travel credit back with the difference. Most airlines don’t charge for change fees on main economy tickets, meaning you won’t be spending more to save.”
