I said the boarding was just par with other airlines, but I can't think of a way to improve it.

I said the boarding was just par with other airlines, but I can't think of a way to improve it.

It was great, but the wifi service was very hard to pay and I barely could use it during my trip. The seats are also a bit tough for tall people (economy area). Other than that, it was a pleasant experience.

The airline was very clean, and the crew very kind and thoughtful.

Enjoyed flying Japan Airlines! Staff were all nice & flight was comfortable.

Particularly meals were great. Service’s were excellent as usual. .

Great easy And smooth check in boarding and flight. Great experience. The allergen free meal was good because I could eat, but flavor and texture left a bit to be desired.

Just a little puddle jumper from Los Angeles to Vegas. Not much can be said, I had to go ask for some water.

The flight was pretty much as expected. Have spent a lot of time flying back and forth from Asia to the US. So it was normal, as usual, most Asian airlines do not have good food, of course, most airlines don't have very good food something to do with 30,000 feet in the air. The seats were a little cramped but that's kind of normal for economy class. Their notification of where to pick up baggage was really screwy. I had to run all over Harry Reid Airport in Vegas to find my baggage. A little better communication about that Would have been much nicer.

The flight was delayed almost three hours because of a labor issue. During the delay, JAL staff did a poor job communicating with customers about what was happening and seemed confused about what to do.

Wonderful service from timely boarding, to attentive crew, food service, my seat was very comfy, no complaints at all!

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Check in desk people constrained by fear. Obvious typo on Uganda visa, even though approved, caused loss of flight. Something is definitely wrong with this system.

Between Air India and Qatar my luggage was lost for three days. I eventually found my own luggage location using the Apple Air Tag. Air India used a paper form to report my lost luggage. I could never get past getting past luggage personnel with my report number before they would hang up on me. Only after them specifically telling Air India at Chandigarh airport where my luggage was located which was right under their noses did they react. After three days I finally received my luggage. The Air India luggage folks didn’t seem proactive in finding the luggage’s rightful owner.

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

I did not like the quality of the food and there was no snacks offered between meals.

Awful seats, poor air circulation. Smelled like poop for 3-5 mins after someone used the bathroom. Child screaming for 13 hours

Temperature in plane in both segments was warm. Otherwise, great experience

Stale, bad and limited food, drink options. Entertainment system was broken, old and had barely any latest contents.

Love that they had a bassinet for our child during the flight. Thank you for that big time.

We are thankful for the useful gifts provided by the airline.The entertainment and crew were also very good

The flight encountered weather turbulences and it was scary at times but the pilot was outstanding! The food is outstanding! The crew was great. Only thing is the flight path map could be better (Reference: Emirates) Also would be nice to have more choice of soft drinks during the flight since it is a long flight. If the crews coming around with water instead of us going to the crew area asking.

Amazing, great airlines to go in business class. Hospitality is amazing. Food is great and lounge in Istanbul is at another level.

Crew was not proactive and were busy laughing and talking instead of attending the passenger’s needs. Meals were served in a hurried manner.

Overall it was a pretty good experience until I arrived in Accra and my suitcase was left in turkey.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

I am not an electronic savy. I don't know how to maneuver the APPS for services. Why can't I just buy food without the apps.

Quality of service and maintenance has declined since my last trip before COVID.

Flight home lot's of room shame I never noticed that they ripped my suitcase and didn't notice it to I got toy destination and had to buy new set

I was pleased and I had a very good experience. The staff was friendly and attentive.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

Flight delayed. They made no attempt to get our luggage to our connecting flight so I am without necessities after they begged me to check in my bag. Still dont have it.

The flight was very good. Only complaint was that the usb charging connection did not work for either me or the seat next to me so we both had to use our own portable battery to charge our phones. I also liked the fact that I could purchase Wi-Fi for an hour instead of for the entire flight.

Your seats in the last 5 rows are terrible. My knees were jammed into the seat in front of me and the lady sitting there decided to recline it. Jammed my knees bad. I don’t know if I’ll fly United again.

The flight from Cleveland to Newark was great. The connecting flight wasn’t so good.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

Service not nearly as good as Qatar airways flights used to be on service from PHL to DOH.

No choice of meal in first class. Was the worst meal I’ve ever had in first class.

Experience was fine. Seats were cramped, and we had to wait for repairs before we could take of. Even though the door remained open, we were warned that leaving the plane could cause difficulty trying to fly out later. Staff was pleasant, and climate control was fortunately working. We had trouble at the DFW terminal, but I don't think that was AA's fault.

No complaints. Good WiFi, great crew and excellent speedy baggage claim

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

temp inside the plane was very hot and could not be adjusted.

The flight crew was fantastic! Which the seats had a small TV.

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.
