I do the same thing on the PA ... That is blame another airline ... Ladies and gentlemen I apologize for the abrupt stop. It seems the Southwest plane failed to stop short of our taxiway as he was instructed. Or approaching the T gates in Atlanta ... Ladies and gentlemen I apologize for the abrupt stop. The Delta baggage cart failed to give way to our aircraft as he is supposed to do.
Always follow up with the call to ATC as to what happened and that we need to check for injuries.
