I did not have a good experience with Delta Airlines during my recent trip flying from Daytona to Atlanta to Rochester Minnesota. I flew first class and found the seats to be very uncomfortable and the flight attendants functioned like unhappy robots.
Coming home waiting for my connector flight to Daytona the gate d8 had minimal seating and most of us had to stand for an hour. I had just had surgery at the Mayo Clinic and overall just got a really bad vibe from the Delta experience. From now on Delta will always be my last choice.
They are not consumer-oriented. The charging ports on several planes did not work and the planes just seemed old and very low-tech.
