Airline reviews

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 Food options are subpar, the overall ambiance feels cheap and outdated, and the cabin design reflects a past era rather than current premium expectations.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.

Our flight was delayed by one hour. Luckily, we were still able to make our connection. This flight is really an Alaska Airlines flight and not the same excellent service and comfort as Japan Airlines.

Very comfortab flight. The flight crew and service was terrific. The food was average at best.

First time flying. Very comfortable, plenty of leg room in economy. The food was good, as well as the snacks. Quick flight back from Kansai to HNL.

Excellent service, excellent food and beverage options, plenty of legroom

I wouldn’t know, I tried to contact you days before to reschedule my flight back to Okinawa but you left me on hold for 2 hours. I tried calling multiple times and not once did you pick up. I had to spend 2000 dollars on a one way ticket back to Okinawa because I couldn’t get ahold of you guys to change my flight.

Crew was tired as we all were. Pretty abrupt. Flight was delayed. Not as enjoyable as the other 3 legs we flew.

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

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

I couldn’t make my first flight due to weather delays trapping us in the town we were in. Then I had to buy a new ticket

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

Chargers didn’t work, no entertainment and we had to wait for taxiing for easily 40 minutes after arriving early. Bags were late too!

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.
