You shouldn't be so generous with your support of American. Stuff like this happens (disproportionately on airlines with relatively poor maintenance strategy/ops like American) , but other mainline US airlines rebook passengers on other available flights. American will simply force all coach passengers (unless a high-level elite) to wait (or rebook on an airline that works with their own money). Doug Parker (a proud 3 time recipient of a DUI, something that American/US covered up but should be front and center for a person in a position of immense trust) must enjoy counting pennies while losing dollars. My own personal experience with American after this New Year (paid big time for a direct flight to get to work, I have the credit card, but was laughed when asked to be rebooked for a never ending delay) . Now I'm willing to pay an even higher premium to fly Delta, Southwest, JetBlue, and Alaska. Heck, I think some airlines (Delta in particular) should support stronger passenger rights legislation as their rivals will loose far more!
