There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Space and comfort was good. Staff could have been more helpful and friendly.

Crew was not friendly when I went to request a seat change.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Quit making seats narrower and narrower. The guy beside me spilled over in to my seat.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

American Airlines canceled the flight twice and was unable to facilitate a change of city for us after our travel plans became affected. We lost alot of money due to this and it seems like the airline was trying their best not to facilitate this. Mind you, I am a very loyal member.

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Disastrous boarding. Entered air bridge only to descend stairs and enter a bus. Plane had insufficient storage, was old and chair recline was damaged. Air stewardess was sullen.

I wish to bring to your attention an incident involving a flight attendant that occurred on my recent journey. The attendant displayed a lack of courtesy, which was concerning. For instance, after accidentally spilling water on a passenger, the attendant dismissed the situation rather than offering a proper apology. Additionally, when I handed over my trash, the attendant reacted negatively because I placed a paper cup on the tray, she told me this doesn't go here and threw it back on my table. It was apparent that she was experiencing a challenging day, which unfortunately impacted the service provided to myself and other passengers. While I understand that everyone can have an off day, it is essential for customer-facing staff to seek support to manage personal stress without it affecting their professional responsibilities.

The flight crew was good, the flight itself was quick and comfortable

Boarding was late by 30 min due to a bus missing to take us to the plane... And then the flight was delayed by about 90 minutes, in a 60 min flight

Very agressive with bags both arrival and departures found minor damage to my luggage including my check bag being broken into nothing of value was in there so I do not believe anything was taken but definitely broken zipper into the outer pockets of suitcase

Everything was nearly perfect, and TAP staff were especially helpful when we missed our connecting flights and had to get on the next flight to Rome. The only aspect that could have been better was boarding: it was somewhat disorganized, which created a bit of stress. But in the end, everyone got on the plane, so the less-then-perfect boarding process did not take away from the overall excellent experience.

TAP Air makes you take a bus on arrival or departure, making it difficult for passengers to make connections.

Two of three flight attendants were not super kind as I would expect. The very kind young lady in my section was wonderful but then lady and man up front were not. Sorry but it makes a difference !

Great staff who were ready working with smile 6 in the morning on New Year’s Day. Although security checkpoint was way too busy, the airline staff were understanding and waited few minutes after boarding. We took off not only exactly on time, but arrived 20 minutes early. Two thumbs up!!!

They allowed some guy to move seats after 3hours of him being next to someone very sick, There were several empty seats, but they moved him to mine. I find that incredibly inconsiderate and should not have been done.

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.
