Delta Service is excellent

Aug 29, 2019

Greatly appreciated a direct flight IAD to SEA (or DCA to SEA) Please keep this running

Aug 22, 2019

It will be better of they allow us to chose our seats when we buy the tickets.

Nicest flight attendant ever

The flight crew made the flight fun.

Delta is definitely doing things to differentiate themselves. Nicely done!

Didn’t like not getting my seat until check in. Especially since I was flying w my 7 year old. Wasn’t sure we would be put together.

Dec 21, 2018

Pilot did an amazing job keeping us safe by aborting landing in heavy wind at Seattle airport and flew to Vancouver. He had big challenges on all ends and really did a fantastic job. We all applauded when we finally got back to Seattle. Bravo!

Please have earphones available for purchase in case passengers forget theirs. Thank you

The seats need to be wider. I’m not 18 and a size 32 waist anymore
