I booked a ticket with an expiring certificate (purchased with expiring points the year before). The flight now has an over 2 hour schedule change. Per AA rules, I believe I should be able to change to a different flight between the same airports, or get a refund. Obviously a refund of an expired certificate is not a very useful refund. Has anyone tried to ask them to use the certificate for a different destination? What do they usually do in this situation?
