Moving a trip by a day or two is often the single biggest saving available, more than any booking trick.
Tools to use
- Calendar / date grid: shows fares for each departure and return combination.
- Whole-month search: for when only the month is fixed.
- Explore / "anywhere": when you're flexible on destination too.
Patterns that often hold
- Midweek and Saturday departures are frequently cheaper than Friday and Sunday.
- Flying on the holiday itself (like Christmas Day) can be cheaper than the days before.
- Red-eyes and early-morning flights are often cheaper.
Patterns vary by route, so look at the grid rather than assuming.
