Aeromexico Change Flight​
There is no modification fee for an Aeromexico flight if a reservation is modified within 24 hours of the original purchase date and the departure date is seven days or later.
One may apply for the Aeromexico change flight charge waiver if they are affected by horrible occurrences like a family death, a jury summons, medical treatment that interferes with a travel schedule, severe weather delays, an emergency or riot-like situation, and many other things.
Passengers are exempt from paying the Aeromexico Airlines change flight fee if they modify an existing reservation in a way that is likely to result in an unavoidable modification to the schedule.
