I received a flight time change notification on an award ticket and called in trying to use the change as my reason to cancel, thinking they would waive the $150 fee. Escalated to supervisor but was told "4 hour minimum" time change required for waiving fee. Let me start by saying it was only a 5 minute change, so I know its a rather weak leg to stand on. Is there really a 4 hour rule, or is it a Continental urban legend? If it is a rule, please copy/paste or link. And any other ideas how to cancel the ticket without incurring the fee?
