Same Day Change fees by airline

Verdict: This fee category is where airlines tend to monetize confusion. Don’t trust the base fare — price the trip as base + likely add-ons.

Pro-Tip: Use airline-specific pages to verify what applies to your fare class and route before purchase.

Loophole: If you fly the same airline repeatedly, co-brand cards and status benefits are the most repeatable way to cut fees over time.

What to watch: Look for route carve-outs, fare-family differences, and whether the airline uses the fee to push upgrades.
