Money-Saving Travel Guide: Expedia data reveals Saturday flights average 17% cheaper than Sundays while booking on Sundays saves 6-17% versus Mondays/Fridays
Published: December 29, 2025 Source: Expedia 2025 Air Travel Hacks Report, NerdWallet, Going, Dollar Flight Club Key Finding: Saturday flights are cheapest to fly, Sundays cheapest to book Savings: $100-400 per ticket with strategic timing
Saturday flights average 17% cheaper than Sunday departures for domestic travel, while booking flights on Sundays rather than Mondays or Fridays saves travelers 6% domestically and 17% internationally according to Expedia’s comprehensive 2025 Air Travel Hacks Report analyzing millions of flight bookings to reveal data-driven strategies for securing the lowest airfares in 2026.
The findings debunk the persistent “Tuesday at 3 PM” booking myth while confirming that flight timing—both when you book and when you fly—significantly impacts costs, potentially saving travelers hundreds of dollars per ticket on 2026 international trips, domestic vacations, and holiday travel despite ongoing operational challenges affecting airline schedules.
“Flight prices change constantly and at all hours of the day, adjusting to real-time demand,” explains NerdWallet travel experts. “Airlines don’t restock on the same day every week like a grocery store, so you won’t find deals by waiting until Tuesdays to book. However, you might find some modest savings if you’re willing to fly on Saturdays or midweek, when there’s less demand than usual.”
Saturday averages the overall cheapest flights by nearly every metric, saving travelers approximately 17% compared to the most expensive travel day (Sunday) according to Expedia’s analysis of domestic flight pricing patterns.
Why Saturday flights cost less:
Real-world savings examples:
Saturday sweet spot: Afternoon/evening departures offer best combination of price and convenience, avoiding red-eye fatigue while maintaining low fares.
If Saturday doesn’t work, Tuesdays and Fridays offer next-best pricing according to Expedia data:
Tuesday advantages:
Friday advantages:
Sunday departures: Most expensive domestic travel day Why:
Monday departures: Second most expensive Why:
Price premium: Expect to pay 15-20% more flying Sunday/Monday versus Saturday for same route.
Contrary to the “Tuesday booking” myth, Expedia’s data reveals Sundays deliver best booking prices:
Domestic flights booked on Sunday:
International flights booked on Sunday:
Why Sundays work:
“The old ‘Tuesday at 3pm’ booking advice is completely outdated,” confirms Going travel experts. “Modern airline systems don’t release inventory on specific days or times. Instead, they adjust continuously based on sophisticated algorithms that analyze demand, competitor pricing, and market conditions in real-time.”
What changed:
Bottom line: While Tuesdays aren’t magical, Sundays statistically offer better booking prices according to current data.
Recent analysis suggests booking between 8:00 PM – 11:00 PM local time can yield marginally better deals:
Evening advantages:
Reality check: Evening timing offers modest 2-5% additional savings at best. Sunday booking matters more than specific hour.
Sweet spot: 44 days before departure (approximately 1.5 months)
Booking timeline:
Example domestic booking strategy:
Pro tip: Domestic pricing fluctuates more than international. Set fare alerts and book when you see good price, even if outside ideal window.
International flights require longer planning horizons for optimal pricing:

Asia:
Caribbean/Mexico:
South America:
Australia/New Zealand:
Holiday periods require earlier booking despite being “domestic” timeframes:
Thanksgiving flights:
Christmas/New Year flights:
Spring Break:
Summer vacation:

Example savings:
Who should do this: Remote workers, retirees, teachers during breaks, anyone with schedule flexibility.
Layover savings: 22-25% average versus nonstop flights
Example:
When it’s worth it:
When to skip it:
Secondary airport savings: 15-30% depending on route
Major city alternatives:
New York area:
Los Angeles area:
Chicago:
Bay Area:
Factor in: Ground transportation costs, time to reach alternative airport, parking fees. Sometimes primary airport still wins on total cost.
Open-jaw definition: Fly into one city, return from different city
Example:
Best use cases:
Booking tip: Select “multi-city” instead of “roundtrip” in flight search engines. Many travelers never check this option.
Automated monitoring beats manual checking:
Top flight deal services:
How to use effectively:
Mistake fare gold: Occasionally airlines accidentally publish fares 50-90% off. These last hours, not days. Deal services catch them first.
The myth: Airlines track your searches and raise prices if you keep checking.
The reality: Multiple studies show price differences from clearing cookies or using incognito mode are negligible—typically within normal price fluctuation ranges that occur naturally.
What actually causes price changes you notice:
Verdict: Clearing cookies doesn’t hurt but doesn’t meaningfully help. Your time better spent comparison shopping across airlines/dates.
Why these months are cheapest:
Savings: Domestic flights 10-15% cheaper than December; international 15-20% less
Best destinations:
Exceptions: Martin Luther King Jr. weekend, Presidents’ Day weekend (minor price bumps)
Why these months offer value:
May advantages:
September advantages:
Savings: 20-30% versus peak summer months

Strategic flight booking in 2026 requires understanding three key variables: when you book, when you fly, and where you’re going. Expedia’s data conclusively demonstrates that flying Saturdays saves 17% domestically versus Sundays, while booking on Sundays saves 6-17% versus Mondays/Fridays—simple changes potentially saving families hundreds of dollars per trip.
Key takeaways for 2026 travelers:
âś“ Fly Saturdays for maximum savings (17% less than Sundays) âś“ Book on Sundays for best prices (6% domestic, 17% international savings) âś“ Avoid Sunday/Monday departures (most expensive days) âś“ Choose midweek flights (Tue/Wed save 13-20%) when possible âś“ Book 1-3 months ahead for domestic, 3-6 months for international âś“ Consider layovers (save 22-25% versus nonstop) âś“ Fly January-March or August-September for lowest annual prices âś“ Avoid June-July and December (peak pricing periods) âś“ Use flight alerts to catch deals and mistake fares âś“ Be flexible with dates, times, and nearby airports
The “Tuesday at 3 PM” booking myth is dead. Modern airline revenue management systems update prices constantly based on hundreds of variables, not weekly schedules. Success comes from understanding broad patterns (Sundays good, weekends bad) and monitoring specific routes you care about.
For Americans planning 2026 international adventures, domestic getaways, cruise vacations, or holiday travel, applying these evidence-based strategies can reduce airfare costs 15-40% versus booking randomly—savings that translate to better hotels, more activities, or simply keeping money in your pocket.

Final Pro Tip: Set Google Flights alerts for your top 3-5 desired destinations with flexible dates (±3 days). When you see a price drop alert, book within 24 hours—exceptional deals rarely last longer. The best flight price is the one you actually book, not the hypothetical perfect deal you wait for that never materializes.
