Boarding was done by woman who insisted on strict standing in line policy; food was ok; entertainment minimal

The boarding and new bag drop-off process was confusing and causing massive delays.

Wider seats, better seat cushions, (I felt like there was a board I was sitting on). I had the chicken to eat but It neither tasted nor looked like chicken. The fruit was good.

It was a very good flight, no entertainment is the reason for not checking that box.

I was in the last row and they sent me to check in my luggage last minute after boarding. I had to go through the crowd.

It was good, however the airplane was really cold. We received snacks and the crew was friendly.

Delta has an outstanding service. They are courteous and punctual most of the time. The flight departed a half hour late but we arrived 15 minutes early.

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.
