Great service but food taste and options have gone down a few notches.

This airlines is always my favorite. Very consistent customer service and food is good. My last flight with them, I had no idea we landed because it was just that smooth of a land.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

More updated movies & Chinese movies. The food sometimes overcooked. Prefer to have more neat snacks in between than just choose from the menu. Please change the menu every now and then. This is my second time flying within one year and the menu didn’t change at all!

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

l enjoyed the variety of good and drink choices. The flight attendants were very quick and efficient to our needs.

Truly impressive service in the air. After the main meal, they have a delicious a la carte menu that you can order anytime until 1.5 hrs prior to landing. Flight crew were so pleasant and very efficient. Wish I could fly JAL more often!

Japan airlines is excellent. I had a great flight with them, and they are the consummate professionals. I booked my flight through Kayak and they sent it on to Underpricer. That felt really scammy. My Oneworld number would not attach to the reservation and I could not choose a seat. I called Japan Airlines and got one but it was in the back. Later I drove to the airport and worked with the excellent agents there to find a better one. Later that day, I got a phone call from Underpricer trying to upsell me the option of choosing a seat. It felt like a Spirit Airlines level crappy move. The flight itself was exactly as nice as you would expect from JAL. The meal was good and the flight crew was awesome.

This flight was operated by American Airlines. AA was completely unprepared for the crowds at DFW for Spring Break and were ridiculously understaffed. They had only three operating kiosks for self check-in, and ONE agent to handle hundreds (thousands?) of dropped off bags. She also had to do double duty to assist passengers at the kiosks. In comparison, flying on United Airlines at Christmastime was a much smoother experience.

Need new movies, a lots of them are 20-10 years old or older. It us a very long flight we need good entertainment. Please load more new movies!

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

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

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

They shld provide food. Between food they are giving 10 hours gap which is toooo much

The crew was great and the food and liquor offerings were good. Seats were a bit cramped. Flight arrived early at destination. That's a plus.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

I had already opted for Vegan food before 2 months yet they say we have no record for it,

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

I like the non stop flight to Lagos. The cabin crew were great, the food was alright and the ride was smooth. The downside is there wasn’t wifi connection from Lagos to Washington as stated. The 11hrs flight, became boring at times because of no wifi.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

One of the best flying experiences I’ve ever had.

The flight cancellation and process for getting a new flight was not that clear. United also had some delays that were unexpected. I am the most disappointed by the fact that I originally bought a Lufthansa ticket, only to be flown by United.

Need to have more snacks for the duration and coffee.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

On time - really well operated flight. Friendly staff. Super impressed with United on this round trip.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

Nice aircraft. Plane was PACKED full and distance between seats was tight. Had it been more than a two hour flight it would not have been tolerable. I had much more knee space on the JetBlue flight I went out on.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

Their computers were down upon arrival to the airport. They were unable to figure out how to board us. We were delayed over an hour and a half.

Delay. Flight was delayed in Washington.knew that connection was impossible as not enough time to switch terminals. The steward would not let me stay the night. So forced to Dallas.late night, after 10pm.hotel checkin was one hour. Passengers lined up only one girl to checkin at comfort inn. No food availability at that time. Had to leave early at 6:30 am to catch a flight at 8:45. Stressfull.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
