Nice amount of space in economy seat. Very attentive attendants that allowed a seat change that helped several people. Morning meal could have been better.

Nice amount of space in economy seat. Very attentive attendants that allowed a seat change that helped several people. Morning meal could have been better.

No food at all so it was a bit of a culture shock for international travellers with connecting domestic flights.

The foods were lacking in both quality and quantity. I was starving.

My only complaint is that the flight attendant that I encountered was not receptive, unhappy to help me out prompted for help with my carry-on luggage to be put up into the over-head compartment. At time of booking, I’ve informed the customer service about my medical-surgical history necessitating assistance in carrying luggage(s)/baggage(s) especially lifting over head. I know crews’ policy of doing such. But, there should be exception(s) to that rule; a consideration for disabled people.. Especially noting given the passenger’s med/surg’s history. Hope, something will come out of this survey. Thank you for your kind understanding and cooperation regarding this issue. So I can still continue flying with any airlines in the near future.

American Airlines has horrible food. Also, since I booked a trip with JAL for all segments, I was surprised and disappointed I was on American Airlines from LAX to Haneda. I paid for JAL and received a much lower quality.

American Airlines Business Class does not meet the standard it should when compared with Japan Airlines, Qatar Airways, or Air France. The flight attendants often appear disengaged and fatigued, with forced smiles, noticeable attitude, and occasional rudeness. Food options are subpar, the overall ambiance feels cheap and outdated, and the cabin design reflects a past era rather than current premium expectations. Lastly, the aircraft itself felt old and uncomfortable. Overall, the experience is not competitive with what peer airlines are offering today.

This was serviced by American Airlines. Not as great as Japan Airlines. The LAX domestic airport is not a great airport. We needed to take a shuttle to go to the gate. Mind you, this is just a connection, but we had to go to security again, which is a hassle after a very long flight from Japan. It makes sense, for our checked baggage to be picked up and moved to the other carousel for our final destination, but for us doing the security all over again, pointless. We had our boarding passes already when we were still in Japan, yet we had to start from zero again when we arrived LAX. There should at least be a different line for connecting passengers without going out like it’s our final destination. Next time, I will try to book our flights from any foreign countries non stop to my destination.

I really love their services! From checking-in to deplaning, superb! Highly recommended!

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good

I like the intention and service of the flight crew. Japanese values were observed and appreciated as a customer.

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Offered to check carry on to final destination. This is the most absurd thing in the world. I'm carrying on because I need what is in the carry-on. I'm okay with picking up at next stop but then I will be on much larger plane that can accommodate it. Also, if there is ever a change to your flight. Go to the airport and have the people there fix your ticket. Don't do it over the phone or online with United they screwed us up and ended up with flights for our last leg that took off before our first leg.

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

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

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