(parents of your spouse or DP). Parents need to
remain on your traveler list for a minimum of 12
months prior to deletion or replacement.

Parent travel on American and American Eagle
flights is subject to a service charge in addition to
applicable segment taxes and fees. Your parents are
eligible for travel on most other airlines; however,
parents-in-law and parents of DPs are not eligible
for travel on other airlines.
