Google today published its annual holiday travel analysis, placing the average low point for US domestic airfares at 39 days before departure and for trips to Europe at 90 days, based on five years of aggregated Google Flights data, according to James Byers, Group Product Manager for Search.

In Short

Google looked at five years of ticket prices and worked out how many days before a flight tickets are usually cheapest for holidays, summer and different destinations. It matters to anyone buying holiday flights and to travel brands that plan advertising around booking peaks. The main change is that the cheapest period for Christmas trips now arrives about five days earlier than last year, while for trips abroad waiting rarely brings a lower price.

What Google published

The post, titled "Wheels up: Trends and tips for 2026 holiday travel," pairs a booking-timing analysis with lists of destinations showing the fastest growth in search interest. Google's top recommendation is to book holiday flights "ASAP." According to the post, October is when Thanksgiving flights tend to be cheapest, and the sweet spot for cheap Christmas tickets "has shifted even earlier."

Two tools carry the individual version of the analysis. According to Google, travelers who already know their destination and dates can open Google Flights or AI Mode in Search to see a "cheapest time to book" view, which compares current prices with prior years and indicates whether they are likely to rise or fall before departure. The general figures, by contrast, are meant for travelers with flexible dates and come from the five-year dataset of US departures.

Byers also wrote the August 27 post that moved Google Flights price tracking into AI Mode across more than 180 countries and territories, so the holiday analysis arrives from the same author who has been extending the product line it describes.

Booking windows by trip type

Google states each result as the number of days before departure at which average prices reach their minimum, together with a range in which prices stay close to that minimum. PPC Land's coverage of the 2024 edition reported the same measures, which allows a side-by-side reading. The 2024 report drew on four years of data against five now, and the scenario definitions are not guaranteed to match exactly.

Trip type2026 low point (days out)2026 low-price range2024 low point (days out)
Domestic3922-5738
International8950-133101
Thanksgiving3421-5745
Christmas5633-6758
Spring break (March or April)5029-6444
Summer vacation (July or August)2120-4721
Europe9049 or more94
Mexico or Caribbean4324-6944

Against the 2024 report, Thanksgiving moved 11 days closer to departure and international travel 12 days closer, spring break moved 6 days further out, and the remaining categories shifted by four days or fewer. The domestic low point stayed essentially flat at 39 days, which Google describes as unchanged from 2025 even though, according to the post, the window around it is "slightly wider" this year.

Year-over-year claims inside the post

Google made two direct comparisons with 2025. The Christmas low point is five days earlier than last year, and spring break is "a full week earlier." The post does not print the 2025 values, but simple arithmetic implies about 61 days for Christmas and about 57 days for spring break. Read alongside the 2024 figures, Christmas went from 58 days to an implied 61 and then to 56, while spring break went from 44 to an implied 57 and then to 50. Across the three editions, the published figures move by several days in both directions.

The post offers no confidence intervals, sample sizes, airline mix or cabin-class breakdown. That leaves open how much of any single-year shift reflects a change in airline pricing behavior and how much reflects ordinary variation in a fixed-method estimate. Readers comparing editions are therefore comparing point estimates, not tested differences.

What the day counts mean on a calendar

The post expresses its results as days before departure rather than as dates, so a calendar reading depends on the assumed departure day. As PPC Land arithmetic, and assuming departure on Thanksgiving Day, November 26, 2026, the 21-to-57-day range runs from September 30 to November 5, and the 34-day low point falls on October 23. Today sits 52 days before that holiday. For a December 25 departure, the 33-to-67-day Christmas range covers October 19 to November 22, with the 56-day low point on October 30. Google's own summary of "late October and mid-November" is narrower than that span, a difference that may stem from departure dates varying across the holiday period, since the post does not name a reference date.

International trips and Europe

For international travel the minimum arrives at 89 days, but the low-price range stretches from 50 to 133 days out, and according to Google the average price drop within that range is "insignificant." Europe follows the same shape: a low point at 90 days, a range starting 49 days out, and the observation that "waiting rarely pays off." Mexico and the Caribbean behave differently, with the sweet spot at 43 days and a range of 24 to 69 days, much closer to departure than in Europe.

Day of week, routing and nonstop premiums

The post also revisits three pricing questions. On the day of purchase, Wednesday beat Tuesday as the cheapest day to book in the latest analysis, but according to Google "the difference is negligible": a Wednesday purchase saves about 1.4% compared with Sunday, the most expensive day. The 2024 coverage had Tuesday cheapest at 1.3% below Sunday.

On the day of travel, departing Monday and returning Tuesday or Wednesday saves about 14% over weekend flights, according to Google, and up to 20% on domestic trips compared with departing and returning on Sunday. The 2024 report framed a similar comparison as 13% for Monday-to-Wednesday flying against Friday-to-Sunday, rising to 20% domestically, so the metric appears to have been redefined slightly.

On routing, nonstop tickets are 20% more expensive on average than connecting itineraries, according to the post. The 2024 coverage reported a 25% premium.

Google ranks "trending" destinations by the largest year-over-year percentage increase in Google Flights searches, not by absolute volume. The post notes that perennial favorites such as New York and Orlando always draw crowds, whereas the trending lists highlight the places with the largest relative increase in searches compared with 2025.

For domestic Thanksgiving trips departing from US airports between November 22 and November 29, the five destinations are Hilo, Hawaii; Buffalo, New York; Columbus, Ohio; Punta Gorda, Florida; and Greenville, South Carolina. Google reads the list as pointing to a growing interest in "tropical retreats and mid-sized regional hubs."

For international trips departing between December 20 and January 3, covering Christmas and New Year's Eve, the list is Athens, Greece; Québec City, Canada; Rio de Janeiro, Brazil; Hanoi, Vietnam; and Guatemala City, Guatemala. The post describes them as spanning "historic cultural capitals and sunny getaways."

The post gives no percentages or search volumes. A ranking by relative growth can favor destinations with a small starting base, so the lists describe momentum, not market size. None of the 2026 names appears among the 2024 destinations named in PPC Land's coverage, which listed Chicago, Phoenix and Dallas-Fort Worth for Thanksgiving and Manila, Sydney, Mexico City and Madrid for Christmas, although that earlier coverage may not have reproduced every entry and does not state whether the ranking basis was identical.

Context: Google's travel surfaces and ad formats

The analysis lands in a year when Google has pushed more of the travel journey into its own interfaces. PPC Land reported that the Flight Deals tool opened on August 14, 2025 in the United States, Canada and India, and that a November 17, 2025 update extended it to more than 200 countries while flagging direct flight and hotel booking as future plans. The August 27, 2026 release added hotel checkout inside AI Mode through Google Pay with ten US partners, whereas flight purchases still complete on an airline's site or a booking platform.

The advertising side has moved in parallel. On April 30, 2026 Google consolidated hotel and flight ad formats into standard Search campaigns under the label Search Campaigns for Travel. During the second-quarter earnings call, IHG Hotels & Resorts was slated to surface special offers during trip planning in AI Mode, in a pilot format called Direct Offers, in a quarter when Search advertising revenue rose 17% to $63.3 billion.

Consumer behavior is shifting at the planning stage too. A HUMAN Security travel guide found that 44 percent of respondents had already used an AI tool such as ChatGPT or Google Gemini to help plan a holiday, with a further 38 percent having considered it.

Geography limits the new data. The figures cover US departures. In Europe, Google's head of search said in a video interview that compliance with EU competition law removed real-time airfares and the option to search for a trip by date, a characterization critics dispute. The holiday post does not list the markets in which the "cheapest time to book" view is available.

Why the figures matter to the marketing community

Travel is among the heaviest categories in paid search, and booking-window statistics from the dominant search engine act as a shared reference point for planners, travel brands and journalists alike. The numbers describe airline pricing, though, not consumer behavior. No search volume, click, conversion or ad-auction data accompanies them, so the link between the cheapest fares and the periods of strongest advertising response cannot be read from the post.

A second consideration is that one company supplies the dataset, the surfaces where the "cheapest time to book" view appears, and the advertising products sold around them. The post describes its method only as five years of aggregated Google Flights data, and outside parties cannot reproduce the estimates from what is published.

Finally, the width of the ranges matters as much as the low points. International and Europe-bound fares sit in a plateau stretching from roughly 50 to 133 days out, whereas Thanksgiving and summer windows are tight, running 21 to 57 days and 20 to 47 days respectively. Where the plateau is wide, a single low-point figure overstates how precisely the best price can be timed.

Timeline

Summary

Who: Google, through James Byers, Group Product Manager for Search. The figures concern travelers departing from US airports, and they bear on travel advertisers, airlines, hotel groups and booking platforms.

What: An annual holiday travel analysis giving average lowest-price points, by days before departure, for domestic, international, Thanksgiving, Christmas, spring break, summer, Europe, and Mexico or Caribbean trips, along with day-of-week savings, a 20% nonstop premium and five trending destinations each for domestic Thanksgiving and international year-end travel.

When: Today, October 5, 2026. The Thanksgiving ranking covers departures from November 22 to 29, and the year-end ranking covers departures from December 20 to January 3.

Where: US departures, published on Google's blog and tied to Google Flights and AI Mode in Search. The post does not state in which other markets the "cheapest time to book" view is offered.

Why: Google presents the data as a guide to booking earlier for Christmas and for trips abroad. It lands as Google moves price tracking, hotel booking and travel ad formats deeper into Search, and the post leaves methodology details and any advertising measurement unaddressed.
