The best time to book flights is usually a few weeks to a few months before your trip. Booking six months ahead isn’t ideal, and waiting until the last minute rarely works out. The right timing depends on your destination and travel dates. If you get it right, you can save real money.
What surprised me most is that five years of Google Flights data show the day you buy your ticket doesn’t make much difference in price. However, the day you choose to fly can lower your fare by up to 20%.
If you’re planning to fly home for Christmas, the lowest fares usually appear between late October and mid-November. That means now is the best time to look.
Let’s go through this together! I’ll cover the best times to book, common myths that can cost you money, and the tools I personally use.
Best Time to Book Flights: The Quick Answer
- Domestic flights: about 39 days out (good range: 22–57 days)
- International flights: about 89 days out, but earlier is safer
- Europe: about 90 days out. Waiting rarely pays off
- Mexico and the Caribbean: about 43 days out (24–69 days)
- Thanksgiving: about 34 days out (21–57 days)
- Christmas: about 56 days out (33–67 days)
- Spring break: about 50 days out
- Summer (July–August): about 21 days out (20–47 days)
Think of these as a compass, not a crystal ball. Your route can behave differently.
How Far in Advance to Book Flights
Domestic Trips: The Three-to-Eight-Week Sweet Spot
If you buy too early, you might pay what I call a planner’s premium. If you wait until the last week, you’ll pay a panic premium. Tickets bought within 7 days of departure have cost about $200 more than those bought at the best time.
Imagine you’re flying from Salt Lake City to Orlando for a Disney trip in mid-March. Start checking fares in early January and try to buy your ticket by early February.
International Trips: Early Beats Clever
Google found that international fares drop only a little between 50 and 133 days before departure. Their advice is clear: book as soon as you can.
If you’re planning to visit Paris next summer, don’t wait for a miracle sale. When you see a fair price, go ahead and book it.
Why Do Studies Disagree?
Expedia might say that international fares are cheapest just 8 to 15 days before departure. But that number is based only on bookings from Expedia’s site, not the entire market. I wouldn’t risk a planned family vacation on a last-minute deal.
When to Book Holiday Flights (Time’s Running Out!)
Thanksgiving 2026
Thanksgiving is on November 26 this year. Ticket prices usually hit their lowest about 34 days ahead. You still have time to get a good deal, but that window closes in about a week.
Christmas and New Year’s
The best deals show up from late October to mid-November. This is about five days earlier than last year’s data. Waiting past mid-November means taking a chance on higher prices.
Summer Vacation
There’s something different for summer: July and August fares usually drop to their lowest just 21 days before departure. But if you’re traveling as a family and need four seats together on a busy route, waiting can be risky. For peak travel, Going suggests booking 3 to 5 months ahead for domestic trips and 4 to 10 months ahead for international trips.
Cheapest Day to Fly vs. Cheapest Day to Book
When You Buy: Mostly a Myth
“Book on Tuesday” is outdated advice. It comes from a time when airlines updated fares on Monday nights.
- Google Flights: Wednesday is cheapest, but it saves only about 1.4% compared with Sunday
- Expedia 2026: Friday is cheapest, saving about 3%
Two major studies found different cheapest days, but the savings are small. That says it all.
When You Fly: This Is Where the Money Is
- Leave Monday, return Tuesday or Wednesday: about 14% cheaper than weekend trips
- Domestic midweek trips vs. Sunday-to-Sunday: up to 20% cheaper
- Tuesday domestic departures: about 14% less than Sunday
If you can change your return from Sunday to Tuesday, you’ll save more than by picking a special booking day.
Cheapest Months
- January is the cheapest month for domestic flights, about 19% below December
- For overall travel, August came out cheapest in Expedia’s 2026 data
- July and December are usually the priciest
The Best Cheap-Flight Tools (and When to Use Each)
You don’t need a bunch of apps. Just pick the right one for what you need.
Google Flights: Your Starting Line
- Date grid and price graph: cheap days pop out in seconds
- Track prices: follow exact dates, one specific flight, or “Any dates” if you’re flexible
- Price history: shows whether today’s fare is low, typical, or high
- Price Guarantee badge: If a fare with this badge drops, Google pays you the difference. There are a few catches: the drop must be at least $5, you can get up to $500 a year, and you’ll get the money only after you fly.
Google Flight Deals: For “Anywhere Warm” Dreamers
Just describe your trip in simple words, like “a week somewhere warm in February, nonstop from Salt Lake.” The AI will suggest cheap places to go.
Skyscanner: Best For Flexible Dates
- Whole Month view: see a full month of prices at once
- Everywhere search: your home airport to anywhere, sorted by price
KAYAK: Best For Second Opinions
- Price Forecast: predicts whether a fare will rise or fall in the next 7 days, with a confidence score
- Hacker Fares: pairs two one-way tickets, sometimes on different airlines, to beat a round-trip price
Momondo: Worth One Last Check
Momondo ranked first in Frommer’s 2026 airfare site tests, while Google Flights came in fourth. It’s worth checking your fare on Momondo before you buy.
Going: Best For Deal Alerts
Going only sends deals at least 40% off normal prices.
- Limited (free): domestic deals within the continental U.S.
- Premium ($49/year): international deals plus mistake fares
- Elite ($199/year): adds business and first class
Just a heads-up: Going works best if you’re flexible. It’s not as helpful if you need to fly to Orlando on specific dates.
Hopper: Use With Caution
Hopper’s Price Freeze lets you lock in a fare for a fee, but the coverage has limits. Some users say it only covered part of a price increase. Make sure to include that fee in your total airfare.
My 7-Step Process for Booking Flights
1. Figure out the best time to book. Check the quick-answer list above to help you decide.
2. Start looking early. Set up Google Flights alerts a few weeks before your ideal booking time.
3. Be flexible with your travel dates. Look at the date grid to compare prices, especially for midweek trips.
4. Look at flights from nearby airports. Fort Lauderdale, Orlando, and Las Vegas usually have fares about 25% lower than the national average. If you’re going to Disneyland, compare the total cost—including transportation—for LAX, SNA, and LGB, not just the ticket price.
5. Search for the actual number of people traveling with you. Airlines price seats in groups, so a cheap seat for one person might not be available for four. If you see a lower price for one seat, try splitting your group into two bookings. Keep in mind that separate bookings might get split up if there are travel disruptions.
6. Decide what price works for you. For example, if your budget is $350 and you find a nonstop flight for $315 with bags included, go ahead and book it.
7. Book your flight directly with the airline. After that, follow the 24-hour rule explained below.
The 24-Hour Rule: Your Free Safety Net
If you buy a ticket at least 7 days before your flight, U.S. airlines have to let you either cancel within 24 hours for a full refund or hold the fare for 24 hours without payment. They only need to offer one of these options.
One thing many people overlook is that this rule doesn’t apply to online travel agencies or third-party sellers.
Here’s my “book and keep hunting” trick: Book your ticket directly with the airline, then set a phone alarm for 22 hours later. Check the same flight again. If the price has dropped, cancel and rebook.
Cheap-Flight Traps That Eat Your Savings
- With basic economy, that $40 you save can vanish once you add seat and bag fees. Plus, you usually can’t rebook if the price drops later.
- For self-transfers, Google’s “Cheapest” tab might show separate tickets that require you to re-check your bags.
- Skiplagging is legal, but it goes against airline rules. Your checked bags will go to the final city on your ticket, and if you skip a leg, the rest of your trip—including your return—will be canceled. If you’re traveling with a stroller and suitcases, it’s best to avoid this.
- Incognito mode doesn’t stop airlines from raising prices. They don’t increase fares just because you searched a few times.
What Most Guides Overlook: Airline Fares Are Becoming Smoother
Airlines once set seat prices in fixed steps, sometimes offering up to 26 booking classes on a single flight. Now, many are switching to continuous pricing, which allows them to adjust fares in smaller increments as you search.
So what does this mean for you? Prices now change more frequently and by smaller amounts. Keeping several tabs open and checking back later isn’t as effective anymore, but setting up price alerts still works.
