Seats are uncomfortable and left me in pain in my tailbone area. I got about one hour of sleep.

overall a very good travel experience - left on time, arrived early. Mostly a smooth flight. Polaris seats were excellent, very good service and nice food with options.

Flight delayed and then cancelled (due to mechanical issues + weather). Poor communication. No one there to help with rebooking and accommodations for the night we had to stay in Newark. Our luggage was taken off the original flight and apparently left on the tarmac in the rain. Items were soaking rain. The following day, the flight was also delayed due to mechanical issues. The second year in a row that I had to sleep in an airport flying from Tokyo to Newark due to mechanical issues compounded by bad weather. Partly bad luck and partly just poor service.

Polaris seat is plush and conducive to sleep. Cabin crew was experienced, highly attentive and helpful when any need arose, such as finding a lost phone in the seat mechanism. Food was a disappointment, especially the Japanese items coming out of Newark all seemed a bit overcooked, though the empanada snacks served midway were a hit.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
