Very below average , plane from Dallas to Toyko was very poor designed plane. I had to sit for 13 hours next to fat man. Really bad seat and entertainment screen sucked

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Very crowded flight but what can you expect these days?? Crew was accommodating.

We didn't take off until an hour after we boarded.

The flight crew was rude. We were in first class and no one even offered water until an hour after we were in the air. Horrible experience

Excellent - explanations were clear staff was nice and flight was comfortable

The flight was fine. This survey is not. There is no option for N/A so items which don’t apply to my experience still must be rated. In those instances I give a “3” rating which ultimately skews the results.

The actual trip was fine, however, the changes made to our flights and the layovers were had to endure were awful.

They only offered water for Group 6. Awful announcements from the Crew. Couldn't understand a single word. Barely came by for the trash afterwards. Man, I love water for a premium flight. Wow. Water in a cup.
