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.

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.

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.

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs
