Time to plan holiday trips: The best time to book flights for the cheapest airfare in 2024

It’s time to start monitoring and booking your holiday flights.

At TPG, one of our key goals is to help you find the cheapest airfare. However, your ability to find valuable airline deals depends on a few factors.

Flights during the holidays, spring break and peak summer periods are often much more expensive. There are still ways to hedge your bets and get better deals than others, but some of the common tips people tout are flat-out false.

Have you ever heard that booking a flight on a certain day of the week will yield the cheapest results? Perhaps you’re thinking of a cousin who claims he found a great deal when he checked on airfare prices at 12:01 a.m. on a Wednesday. Maybe your friend swears by setting a reminder on their phone for 1 p.m. on a Thursday when shopping for flights.

There’s just no truth to that legend.

While there is no shortage of rumors (and “studies”), here’s what airfare experts say about how timing influences airfare prices so you can maximize airfare savings.

Right now is just about the cheapest time to book holiday flights

Historical data suggests that the period to find the best prices for domestic holiday airfare is almost upon us. I strongly advise readers to start looking at flights now, set Google Flights alerts and grab deals as soon as you see them.

My best advice for finding the cheapest prices ahead of the holidays is to monitor the search starting three months before each holiday; plan on booking Thanksgiving trips in early to mid-October and Christmas trips by Halloween. Obviously, you should jump on any deals you find before that.

Travel booking site Hopper says the general rule is to book flights between 25 and 150 days prior to takeoff.

That lines up with what Google suggests too. “For trips within the U.S., average prices have been lowest 38 days before departure,” James Byers, group product manager of Google’s search team, said in a 2024 travel trends report. “The historical low price range is 21-52 days before takeoff.”

Based on search and booking data, Google says Thanksgiving prices are lowest 45 days before departure, and Christmas prices are lowest 58 days before departure. The data backs up my suggestion to book Thanksgiving in early October and Christmas in the back half of October.

I’m a huge fan of Google Flights because you can set alerts for particular destinations (like Grandma’s house in Des Moines for Christmas week). For example, I am currently setting alerts right now for flights home to California for the holidays.

In the example below, you can see I set a Google Flight alert for a 12-day trip from Dec. 21 to Jan. 2. Google will send me an alert if the price drops.

Google also tells me that prices are currently “high,” so for me it makes sense to wait.

I also like Google Flights’ feature that lets me see a graph of prices for similar time windows; it might help me decide on which dates to go home for the holidays.

Other tips for holiday flights:

• Use points and miles. Using your stash of points and miles can make a ton of sense when cash prices are high. Remember, one of the core mottos of the points and miles space is, “Earn ’em and burn ’em.”
• Try flying on nonpeak days, going to your destination earlier than normal or staying longer. You’ll often score a better deal if you go home for Christmas for a few weeks rather than a few days.
• If you can fly on the actual holiday itself, you’ll often get a better deal. For example, flying on New Year’s Day or Christmas Eve can save you big bucks.
• Be flexible with days and times. Often, you’ll get the best deal on a flight leaving at 6 a.m. instead of 10 a.m. It can be worth getting up at 4 a.m. to save some cash. Same deal with red-eye flights, which are often the cheapest flights of the day.
• Look for alternative airports. For example, flying into San Francisco Bay Oakland International Airport (OAK) instead of San Francisco International Airport (SFO) can save substantial money.
• Look for deal alerts. Sign up for social media accounts that send out deal alerts, and subscribe to our daily newsletter, where we often publish airfare deals.

Is there a day that’s cheaper than others to book a flight?

It’s a question we get asked all the time: “What is the cheapest day to book a flight?” There’s a common misperception that certain days are better for finding flight deals. However, research shows that this is a myth.

There is no magic day to book, but there are some sweet booking windows when airlines lower prices, according to Lindsay Schwimer, a consumer travel expert at the booking app Hopper.

Hopper relies on 10 years of data and 80 trillion flight prices to recommend the best time to book specific routes and dates.

“Typically, we tell travelers for domestic trips to start monitoring prices three to four months in advance of a trip,” Schwimer said. “Expect to book one to two months in advance.”

For international trips, the booking window is a bit larger. You should start monitoring six to seven months prior to the trip and book it three to five months in advance. That’s the recommendation from both Hopper and TPG.

“When you’re traveling internationally, planning ahead is key to getting the cheapest airfare,” Hayley Berg, Hopper’s lead economist, said in another interview. “Travelers often book international flights too far in advance or too last minute, overpaying significantly for their tickets.”

Remember that the strategy changes pretty dramatically if you book with points and miles. Airlines often open award space for coveted business- and first-class seats either when the schedules open or at the last minute.

As for whether there’s a particular day that’s cheaper than the rest for booking, Schwimer mentioned that “there’s no one day or golden rule when to book.”

Berg echoed this sentiment.

“There’s a common myth that ‘booking on a Tuesday’ will guarantee a traveler the best price,” she said. “The reality is prices change so often and depend on the route, the travel dates, etc., that there isn’t one day that guarantees you the best price.”

What’s the best day to travel?

Although airfare prices fluctuate based on when you book, midweek travel is generally cheaper than flying on weekends. That said, Sundays can also be a sweet spot.

“Flying midweek can save you nearly $100 off your ticket,” Schwimer said. “So when you’re thinking about when you want to travel, try shifting your dates midweek versus flying over the weekend. If you can be flexible and book either a Tuesday or Wednesday versus a Friday or Saturday, you’re gonna save significantly off your trip.”

Berg had similar thoughts.

“Travelers who fly midweek, usually Wednesday, can save an average of $56 per ticket on domestic airfare throughout the year,” she said. “Midweek savings spike over $60 per ticket during busy spring break and summer vacation months, while flying midweek over the holidays can save you $100 or more.”

Schwimer also had some good advice to take the first flight of the day. Often, you’ll find those early departures can save you some big bucks. It’s not easy to set the alarm for 4 a.m., but it’s easier to wake up when you know you’re saving money.

“We always recommend booking the first flight of the day, not only to avoid delays and cancellations but also in terms of price,” she said.

According to Bob Harrell — an airfare consultant at Harrell Associates who analyzes airline pricing — you might also find that airfare prices fluctuate Monday through Friday. That’s because airlines look at customer demand and monitor booking trends to decide whether to open or close certain types of fares and whether to raise or lower existing fares.

So, how can you use this information to your advantage when buying airline tickets?

Try using a price monitoring tool to get real-time updates to help you decide when to travel for the lowest fare. Tools like Google Flights and Hopper’s “Watch This Trip” can help you track the price of your desired route before booking; they will indicate or directly notify you when prices are at the lowest for your trip.

When to book holiday travel

Best time to book flights for Thanksgiving and Christmas

As referenced in more detail above, the cheapest holiday airfare deals are generally available in October.

“We tell people to start monitoring in August,” Schwimer said, “but our typical book-by date is mid-October, so usually around the 14th of October.” She added that “no later than Halloween is usually our book-by date for both Thanksgiving and Christmas.”

Similarly, a Google Flights booking trends report suggests that average flight prices around Christmas are lowest around two months before departure.

Prices will only rise as the holidays approach, so your best bet is to book sooner rather than later. However, I strongly encourage folks to set Google Flights alerts and carefully monitor prices. Better yet, use refundable points or miles in case you find a better deal. You might also want to lock in a lower cash price if you are booking with an airline that will give you a flight credit if the price drops.

Best time to book flights for New Year’s Eve

As with Christmas flights, Hopper recommends locking in bookings for New Year’s by Halloween at the latest.

That is true for “really any of the major winter holidays,” Berg said. “We recommend booking further in advance. I would book that New Year’s Eve trip as well before Halloween.”

Best time to book flights for summer trips

Berg said that prices tend to drop on average one to two months before departure, but last summer, we saw a lot of last-minute travel deals — even to Europe.

“Prices will change frequently,” Berg said. “Don’t wait too long to book, as prices can increase by almost double in the last three weeks ahead of takeoff.”

If you are already planning for next summer, Hopper recommends monitoring flight prices at least three to four months in advance and then booking one to two months before the intended travel date.

If you plan to head abroad next summer, the booking window is naturally further out, particularly for longer-haul transpacific flights.

“For trips to Asia and Oceania, we recommend booking five to seven months before takeoff,” Berg said. “For Europe and other regions of the world, we recommend booking anywhere from three to six months before departure to get the best prices.”

Best time to book flights for spring break

The best time to book your spring break trip is similar to the timeline for summer trips. You should begin monitoring prices for your desired destination three to four months in advance, depending on when your (and your family’s) time off falls. Set Google Flights alerts for upcoming trips you have in mind.

For example, if your spring break falls in March, the ideal time to book is before early February. Flexibility will also help here.

Remember that demand surges during the spring break period after the doldrums of winter. Many people wait too long to book those trips and end up paying more than they need to.

Hopper says airfare prices will fall between one and three months before departure and rise rapidly in the last three to four weeks before spring break.

What about hotels?

Hotels are a special category where you can often wait until much later to score good deals.

“We often see good deals last minute for hotels in big cities. Something to keep in mind … especially for those holiday weekends,” Schwimer told TPG. “And you know that [during] the Christmas holiday period, you can often find some really great last-minute deals in big cities if you wait.

“Obviously, that’s not always ideal in terms of planning,” Schwimer continued, “but we have seen some really great deals in that last-minute window in big metro cities.”

Bottom line

While there is no magical time or day to book airfare for the best prices, your best bet is to fly midweek, specifically on Wednesdays, for both domestic and international travel. Flying over the weekend can come at a significant price premium, though Sundays have occasional deals.

Also, try booking domestic flights one to two months ahead of time.

For international flights, your best bet is to aim to book three to five months ahead of the trip.

If you are using airline miles, remember that it’s never too soon to start checking and booking.
