I'm traveling with a group on American Airlines, Philadelphia to Maui (thru Phoenix) and want to upgrade my seat only on all 4 flights. Group travel at the airline says no problem, plenty of seats available, travel agent has to separate me from the group and it can be done. Agent has been trying for over 2 weeks with no success, just keeps getting runaround. Have emailed customer service as well as contact person at American and have heard nothing (over a week for both). Any help is appreciated.
