We HAD nonstop from PHL in mid November with American. We DID get email notification that we are now laying over in Miami. Our friends also got an email. Not happy. The only other nonstop for our dates is from JFK- (Delta and Jet Blue).
AA gave us only 1 hour layover in Miami. Anybody who flies from PHL knows nothing leaves on time. So we had them change our PHL flight to an earlier flight.
Not fun! Nothing we can do. I asked for waiving baggage fees and/or earlier boarding and was sharply told "NO!".
AA sucks.
