Airline reviews

I will never fly ANA again. They lost one of my large pieces of checked luggage, the heaviest one with the most valuable items in it, and they said they will not send me an email unless they can't find it, even though the paper they gave me to track the status of my lost luggage requires a code from an email they are supposed to send me so I can do baggage tracing. They claim to be an international airline, but they also insist on calling a Japanese telephone number to confirm where to send the lost baggage if they find it. It is impossible to find an actual contact email address for customer support on their website, and their AI chatbot is unhelpful, directing you to a webpage that says it is for contact information but does not have any actual email addresses or phone numbers listed on it. My seat in economy did not recline at all, even though I was not sitting in an exit row nor the very back row. I had to sit in the fully upright position for over ten hours of international travel. Awful experience overall.

The head flight attendant made the trip excellent. He was very accommodating.

The economy seats on the 777 was not as cramped as I had feared, but the food was terrible.

Terrible experience! delay 2 time and say i dont have ticket

It was amazing. I had several upgraded seats on my flight out. Everything went smooth with no delays.

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

Flight attendants were friendly & good service, food sucks, seats uncomfortable, not many Asian movies or shows flying from Hong Kong

Flight attendants had a little attitude. Food tastes no good.

Overall we had a good experience during our flight from San Francisco to Houston.

it was a very short flight so my expectations were low.
