C
8.0 Very good
The flights were on time; all went as expected which is a big positive! No delays! There was no food or drink service in any legs, which I understand due to the short flight time.
J
2.0 Poor
They announced a mechanical issue prior to boarding Said it was fixed, we boarded Waited Then learned it was not fixed Had to deplane and go to new gate Bought wifi on plane and it never worked
J
4.0 Mediocre
The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.
M
10.0 Wonderful
Delta off boarded and boarded the aircraft quickly. Clean cabin and great gate and onboard service.

4.0 Mediocre
The plane is old. There was water dripping fown from the air cooling system. The toilets were mot that clean
S
2.0 Poor
delayed 3 hrs
F
2.0 Poor
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.
