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.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Seats are complete BS for 10 hrs. The guy at counter canceled our return flight from europe. Lufthansa on the way back made United look like a trailer park gathering. If given the opportunity, I will never fly united again. Lufthansa seats werent much better to be fair but the service was a 10 out of 10. Incant express how difficult umited made my trip.

It was a great experience to fly with ANA, the sit is very comfortable.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

Gluten free snack options and meals that offer both gluten free and dairy free.

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