My only dealing of ATC issues on an AS operated flight, I was given full credit for future use.
JFK-SFO: boarded and sat on the plane still attached to the jet bridge. After about an hour, we were told at least another 2 hours due to SFO. AS allowed pax to deplane should we wished and unchecked us upon deplane. I called AS and got a credit. Went home instead of going to SF.
