We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes
A
4.0 Mediocre
The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.
A
2.0 Poor
We were delayed 2 hours because of a broken seat. Other than that it was a very nice flight.

8.0 Very good
There needs to be better accommodations for waiting passengers. A a designated standing space that is separated and away from concourse traffic.
M
8.0 Very good
My seats are comfortable because I choose to fly in the exit rows and this time upgraded to first class with minimum sky miles. Otherwise, I would not be happy in regular seats or even middle comfort seats. Onboarding on the return flight from Nashville to Atlanta was hot and very uncomfortable for over 30 minutes due to extreme hot weather. However, Delta should provide some other air flow option as it was almost unbearable until 10 minutes after take-off. First class seats should be equipped with cup holders. Currently, the middle console is used and is flat and prone to spilling drinks.
E
4.0 Mediocre
Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate
A
4.0 Mediocre
wifi too slow or would not connect and entertainment kept on freezing
A
2.0 Poor
Cancelled my flight. Left me in airport for 12 hours. Rude gate attendants. Worst delta experience I’ve had. I hope they have a focus group and return to thinking about customer service.
