Airline reviews

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

Arrived early, comfortable seats (Comfort+). Mediocre food, poor wifi (intermittent).

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Great crew, flight on time, luggage pick up a breeze

Was on time, normal boarding. The worst flight attendents and service I ever seen,, can't believe Delta can have such service. Bathroom was dirty and no toilet paper, paper towels and used toilet paper all over the floor, when I tried to tell flight attendant she didn't even let me to finish and turn around. Very rude. Wi fi didn't work.

Connection flights should be spaced out farther because too close I missed my connection.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.
