FAQ

Do airline rules replace destination rules?

No. You need both sets: destination compliance and airline operational acceptance. The stricter requirement can block travel.

Can policy details change close to travel date?

Yes. Always confirm current rules directly with the airline before booking, before check-in, and before departure.
