Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

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.

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

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Very easy to use and convenient, you can perform any action within the same portal

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.
