Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

Excellent. There were setbacks, but it had nothing to do with the crew. Mostly, mechanical which delayed our flight.

The flights with ANA were great. The flights with United, not so much.

It was so disappointed trip by unexpected company's fault delay. It had taken 3 hours delay for mechanical maintenance plus another 3 hours for bad weather.

SEA HND sector internet only worked for the last 2.5hrs of flight….. never had this kind of incident with other airlines

12 of the 14 hours were in the dark, all during daylight. Didn’t use my light because it disturbed other people it was illuminating. 14 hours sitting upright in a cramped space was horrible.

I’ve always had pleasant experiences with ANA and that has made me a loyal customer.

They are very helpful and friendly. The entertainment is great with many choices. They will refill your drink and there is plenty of meal service. I’ll fly with them again when I transit Tokyo.

Boarding was quick and efficient. The food was very good and they had pictures showing you what options there were to avoid misunderstandings.

Boarding was fast and efficient. Not a cramped plane and good comfort. Food was great and attendants were very nice.

Again the ANA flight was canceled. Rebooking with Vietnam air was not good. Vietnam air is sub standard. Will not use a third party booking, like kayak again.

Airplane is not very clean, food quality and taste was not good. Lufthansa used to be good but nowadays went down. Overall experience is just okay, wouldn't fly again, prefer Turkish airlines.

I missed the flight due to maintenance issues. This is the second flight I’ve missed in four days because United allows such little time between layovers. Very disappointing

My return flight to Honolulu (UA 1170) was on a 777-200. I’d forgotten the weird seating arrangement in first-class (2-2-2); I was in 1B, so I faced the passenger in 1C. Unfortunately, there was a problem with the flight computer, so we left LA an hour late (6:05pm). The meal I chose was Korean BBQ Glazed short rib. It was served with a nice salad and fried rice. This meal was better than breakfast on the outgoing leg. All in all, a decent flying experience. Ratings: 777: 3.75, food: 3.5, service: 5 (out of 5).

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.

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

Very rough getting into denver. my kid threw up it was so rough.

Liked that we left on time for each flight. Snacks not the best, but we're okay.

I had requested wheelchair assistance prior to flight. The airport staff had no record of it. It was not provided at Cedar Rapids which was a small airport, so I managed on my own. At O'Hare airport the same thing happened. The staff told me they had no record of my request for a wheel chair. But they finally provided it after a delay when I insisted that I needed it.
