Driven by an emergency generated by Delta, we were forced by miscommunication between Delta, its subsidiary Endevour Air, and the Marsh Harbour Airport. While every other plane landing at MHH was turned around loaded with passengers, DL5111 sat on the apron for hours ultimately squandering its opportunity to return to ATL. Delta’s own app communicated confusion with announcements indicating delays. Eventually the airport drove us customers away announcing cancellation of the flight and closing the airport allowing no lingering. If weather had been a factor denying #5111 taking off, it certainly didn’t impede all the other flights to leave.
