Wanna know the best days to book flights to keep some extra cash in your pocket? I mean, who doesn’t love a good deal on airfare, right? Prices can be all over the place, but booking on the right days can save you a bundle. I’ve done a bunch of research, and, I’ve got some stories from my own trips to share. In this post, we’ll cover the cheapest days to book flights, some handy tips, and a few tricks to help you snag travel deals. Let’s jump in!

Why the Day You Book Matters
Airline prices aren’t just random—they’re based on stuff like demand and fancy computer systems. Knowing the best days to book flights can make a big difference. I was reading this Expedia report from 2023, and it said you could save up to 20% just by picking the right day. Pretty cool, huh? Let’s break down why timing is such a big deal.
What’s Up with Airline Prices?
Airlines use these crazy algorithms to set prices, based on how many people are booking, the time of year, and even what other airlines are charging. Prices usually go up closer to the flight date or during busy times, like summer vacations. By picking the cheapest days to book flights, you can beat the system. Once, I saved $80 on a flight to Denver just by waiting til Tuesday to book—true story!

The Best Days to Book Flights for Big Savings
Okay, so when are the best days to book flights? I checked out a few studies, like from Google Flights and CheapAir.com, and here’s what they say:
- Tuesday: Airlines drop new fares late Monday or early Tuesday. Google Flights said in 2024 that you can save about 15% booking on Tuesdays compared to weekends.
- Wednesday: Midweek’s another good one, less people are booking, so prices dip.
- Sunday: Kinda surprising, but Sundays can be great for domestic flights, per CheapAir.com.
Pro Tip: Don’t book on Fridays or Saturdays, those days are pricey cause everyone’s planning their weekend trips.

Cheapest Days to Fly to Save Even More
Booking’s one thing, but flying on certain days can save you even more. Here’s the lowdown on the cheapest days to fly:
- Tuesday and Wednesday: Midweek flights are usually cheaper, less travelers. Like, a flight from Seattle to Miami might be $140 on a Wednesday but $210 on a Friday.
- Saturday: Not always, but Saturdays can be good for domestic flights since business people aren’t flying.
- Skip Mondays and Fridays: These are super busy for business trips, so prices are higher.
Real-World Example: My buddy Lisa saved $130 on a flight to London by booking on a Tuesday and flying on a Wednesday, instead of her first plan, which was a Friday. She used the extra money for some fancy tea in London!

Here’s some flight booking tips to pair with the best days to book flights and save even more:
- Book Early: Try 1–2 months ahead for domestic, or 2–6 months for international flights. Kayak says this can save you up to 30%.

- Stay Flexible: If you can move your dates around, use tools to find the cheapest days to book flights.
