Fare Type Matters Most

Across the industry, the biggest factor in whether a flight change is free, discounted, or full-price is the fare type originally purchased. Basic or "lite" fares are the most restrictive, often disallowing changes entirely or charging a higher fee than standard fares. Flexible or premium fares typically allow free or low-cost changes.

Same-Day Changes vs. Standard Changes

Many airlines distinguish between a same-day change — moving to a different flight later or earlier the same day — and a standard change to a different date entirely. Same-day changes are often cheaper or free on certain fare types, since they don't require the airline to reprice the full itinerary.

Checking your specific fare rules before requesting a change avoids surprise fees — the same request can cost very differently depending on the ticket type.

Fare Differences

Even when a change fee is waived, most airlines still charge (or credit) the difference between your original fare and the new flight's current fare. This is separate from any change fee itself.

Frequently Asked Questions

What's the difference between a same-day change and a standard date change?

A same-day change typically moves you to a different flight on the same calendar day, often for a smaller fee or free on some fare types. A standard date change moves your trip to a different day and is usually priced based on the fare difference plus any applicable change fee.

Do all fare types allow changes?

No — this varies widely. Many airlines offer no-change-fee policies on standard fares, while the lowest "basic" fare tiers are frequently non-changeable or carry higher fees. Always check the specific fare rules attached to a reservation.

How far in advance can I make a change?

This depends on the fare rules and how close to departure you are. Some changes can be made up to the time of departure, while others have cutoffs, such as 24 or 60 minutes before scheduled departure.
