Hi.. This is more of an FYI. I had a ticket on hold from ZUR to BOS on AA.com and it was set to expire at 11.59 P.M. CEST (Central European Summer Time). However AA.com cancelled it before the expiration time. I am not sure how long before it cancelled. I caught it 5 hours before the expiration time and was able to get it reinstated by talking to a supervisor. The regular agents will not be able to help you at all!!
