Anonymous, May 2017

Pros:On board crew was helpful and polite considwring our circumstances.

Cons:Our flight was delayed 3xs (non weather) they said we would miss our connection (I didn't think we would) THEY rebooked a later flight. Of course we landed in time for our original flight. They refused to let us back on our original flight. Put me in touch w/ the help desk who after talking in circles admitted it was their mistake but he had no authority to help. FINAlly & only because others missed their flight we were given the option to go. Crew misplaced our luggage and sent it on a flight we were never supposed to be on, and the bad experience with delays of hours on end continued coming home. (Mechanimal non weather) WE WILL NEVER FLY DELTA AGAIN!
