It is very straightforward when it comes to refunds and cancellation fees. If someone cancels a flight within 24 hours of booking, assuming that tickets were booked at least seven days before the flight, no cancellation fee will apply - the full amount will be refunded. On the other hand, if the Aeromexico cancellation is done 24 hours after the flight or within 24 hours of booking at any time, the cancellation fee will be applicable.
