Key takeaways

Refundable vs Changeable Fares — what matters?

Link to this answer

Refundable means you can cancel for money back (per rules). Changeable means you can keep residual value toward a new flight, often minus a fee. They are not synonyms. Buy flexibility when trip risk is real; skip Flex theatre on immovable dates. Not for everyone — confirm it fits your dates and risk tolerance.

How do you decide if Flex is worth it?

What flexibility traps should you avoid?

Avoid assuming residual value equals a cash refund, missing fare-difference payments on changes, or buying refundable fares without reading the residual rules. Flexibility is a priced product — verify the ticketed rules before you need them. Confirm details on the official site before you buy.
