Finding the cheapest days to fly is one of the highest-leverage things you can do to shrink your travel budget. The exact day you take off can change your fare by hundreds of dollars — even on the same route, the same week, with the same airline.
The cheapest days to fly, ranked
Across millions of fare snapshots on our platform, the pattern is remarkably stable across continents:
- Tuesday — the single cheapest departure day on most routes.
- Wednesday — a very close second, especially for international flights.
- Saturday — cheap on business routes; leisure travelers already arrived.
- Thursday — starts to creep up as weekend demand kicks in.
- Monday — expensive because of business travel.
- Friday — leisure travel begins; prices spike.
- Sunday — the most expensive travel day on almost every route.
Three rules that beat any single "cheapest day"
Focusing only on the day of the week leaves money on the table. Combine these three habits to stack real savings.
Rule 1: Fly Tuesday or Wednesday when you can
A one-day shift from a Friday departure to a Tuesday departure cuts fares by an average of 22% on European short-haul routes, and up to 35% on transatlantic flights. If your schedule allows even a small change, run the search for both dates.
Rule 2: Return on a Tuesday or Wednesday
Round-trip fares are calculated as a pair. If both legs land on cheap weekdays, the total drops even more. Avoid Sunday returns — they are the single most expensive leg on almost every route.
Rule 3: Consider red-eyes and early mornings
Flights departing before 7 a.m. or after 10 p.m. are typically 10–25% cheaper. If the route is short, this is a very small sacrifice for a real discount.
When the pattern breaks
The Tuesday/Wednesday effect softens during peak season. Around Christmas, spring break, and major public holidays, every day is expensive and the differences narrow. For those periods, booking window matters more than day of week — aim to book 4–6 months in advance.
How to lock in the cheapest day for your route
The fastest way to find the cheapest day for your specific route is to use a flexible calendar and a price alert:
- Search your route with a "flexible dates" view to see the whole month at a glance.
- Note the lowest three days — usually clustered on Tue/Wed.
- Set a price alert on that date; you will be notified if it dips further.
Bottom line
The cheapest days to fly in 2026 are Tuesday and Wednesday, with Saturday as a strong runner-up on business-heavy routes. Combine flexible days, off-peak times, and price alerts and you will consistently pay less than travelers who book by habit.

Weekdays are almost always cheaper. Friday and Sunday are the most expensive travel days because of leisure and return-trip demand.
Should I fly at night to save money?
Red-eye and early-morning flights are often 10–25% cheaper than midday flights because demand is lower and airlines discount less popular time slots.

On most routes, shifting your departure by one or two days saves 15–35%. On long-haul international flights, savings of $150–$400 per ticket are common.
