Refer to the Osaka-Tokyo one, it explained how I felt about both flights

Refer to the Osaka-Tokyo one, it explained how I felt about both flights
I am a United 1K flyer but certainly I would fly ANA again. Great inflight service!
"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.
Great. Very helpful staff and accommodating. The flight was also smooth
My son flew and had a great experience.. thank you for taking care of my baby
The flights with ANA were great. The flights with United, not so much.
Choice of movies dated as with the screens. Major room for improvement on the software to sort and select choices.
I loved everything about my experience!!! The staff were absolutely incredible. I can not wait to fly again with them.
Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.
we were in premium economy, but we both got middle seats and had to sit separately. i could have avoided this by trying to obtain seats sooner, but i tried 3 times and gave up. ANA's technology is not friendly for newcomers. no, check that---I think it is nigh impossible. not sure we are coming back. ana can do better to provide a front end that's friendly to users in both US and Japan.
