We booked flights to minimize the lay over time. On the way in our flight was to connect in Minneapolis St. Paul. The flight was late to arrive to Minneapolis, leaving less than 30 minutes for the connection. The flight attendants failed to recommend priority disembarkation, favoring those passengers with connections, they failed to provide someone at the exit gate who could direct us to the correct connecting gate. They also failed to notify the connecting flight that we arrived late and would be on our way. We missed our connection by 2 minutes and had to wait for the next connection for 5 more hours, which ruined our plans and complicated our car rental and hotel booking. We used to place Delta at the top of our list, now it's down the middle. In flight wifi was a myth.
