Cheapest Day to Fly in the USA 2026 | Save Up to 40% on Flights

Timing your flight purchase correctly can save you hundreds of dollars. The day you fly — and the day you book — both significantly impact the price you pay. Here is exactly what the data shows for US domestic and international flights in 2026.

Cheapest Days to Fly Domestically in the USA

For US domestic flights, the cheapest days to fly are consistently Tuesday, Wednesday, and Saturday. Airlines release fare sales on Monday evenings, competitors match by Tuesday morning — making Tuesday and Wednesday the sweet spot for cheap seats.

Best Time of Day to Fly Cheapest

Beyond the day of the week, the time of your flight also affects price significantly:

• Early morning (5-7 AM): Consistently cheapest — less demand, airlines fill seats
• Late evening (9-11 PM): Second cheapest — red-eye and overnight flights
• Midday (10 AM-2 PM): Medium pricing — convenient but more expensive
• Evening peak (5-8 PM): Most expensive — business traveler demand drives prices up

Best Day to Book Flights (Not Just Fly)

The day you purchase your ticket also matters. Research consistently shows:

• Domestic US flights: Book 6-8 weeks before departure for the lowest fares
• International flights: Book 3-6 months in advance
• Last minute (under 2 weeks): Fares spike significantly — unless you call a travel agent who has access to last-minute consolidator inventory
• Tuesday and Wednesday are also the best days to purchase tickets — airlines drop prices after the weekend rush

Does Any Day Beat Consolidator Fares?

Flying on Tuesday saves you 10-20% compared to Friday on the same flight. However, calling ASAP Flight Booking at (844) 603-0034 for a consolidator fare saves you 20-50% on any day of the week — including peak days like Friday and Sunday. Consolidator fares consistently beat the cheapest publicly available fare regardless of when you book or fly.

Cheapest Months to Fly Domestically

• January and February — cheapest months after the holiday rush
• September and October — excellent value, weather still good
• June, July, August — peak summer, highest prices
• Thanksgiving and Christmas weeks — most expensive of the year
