Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

ok, butt flght was delyed for 2,5h from Frankfurt, and next Flight to Columbuse same

Flight was great. Almost miss my connecting flight due to late departure from Haneda. Had to run all through airport in Chicago to make the flight. Experience was great for 1st time flyers using ANA Airlines.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.
