Lost one piece of luggage even though I checked in 2.5 hours before the flight

Lost one piece of luggage even though I checked in 2.5 hours before the flight

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

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

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.

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

Much better than Spirit. I was please by the easy fast check in and boarding

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

One of the best flight experiences I've have had in along time. Would fly with them again.

There was a mixup with our tickets. They said they did not receive payment for them but yet we had seat assignments. We had to purchase last-minute tickets which cost us three times as much. that’s why they got a rated of a one.

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

The flight was delayed significantly. Communication during the flight was abrupt and caused some panic as we were navigating turbulence. It was also too loud and every announcement felt startling. The flight attendants did not offer any assurances and I felt unsettled most of the flight. The seats, floor and tray table was very dirty. The seat next to me was broken and the passenger sitting there was very uncomfortable. He had a spring in his back and his seat made terrible squeaking noises through the flight.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.

It was awful. The communication between corporate and the crew on the ground left more to be desired. The crew even said that Corporate was waiting on answers because they themselves didn't know. Every hour, there was a new excuse. I also understood that passengers were angry, but the crew should have done a better job at crowd control. There was a racial exchange between passengers that could've been avoided has the crew acted sooner.

We sat on plane at gate delayed without communication as to why we were just sitting there

Flight was delayed by 6 hours... the level of incompetence was truly astounding. I won't be flying American Airlines again. I don't care if AA is direct and there is a layover with another airline, I'll take the layover.

Check in was easy. Flights were smooth. Flight attendants were courteous and friendly.

Little time between flight from Dallas to flight to Gainesville. We chose this one, 43 minutes between, because the price for a connection with at least an hour between, was so much higher. Had to ask passengers on the Dallas flight to please allow us to deplane ahead of them. The economy passengers allowed this. We had to walk very fast to the next gate, 35 gates away. Thankfully all in the same terminal. Getting to the small Gainesville plane was a little confusing as you enter an area that is boarding many small planes at the same time. We stood in the wrong line for about 15 seconds before realizing it was not our Gainesville flight. Since I had boarded at this gate in the past, I knew to check the signs carefully so we weren’t lost. The first class seat experience was wonderful. I really enjoyed the upgrade. We were offered an alcohol drink as soon as we sat down. I got something different but it was a great gesture especially since we really had to hurry to make the flight. We had packed expecting we might miss this connection, but made it. Our luggage didn’t miss the flight. American Airlines delivered our bags to our home the next day. That was very convenient!

The plane was large, not full, but one with 3 seats near each window and 4 in a row in the middle of the plane. There were screens on the backs of the seats for entertainment and information. To use the entertainment one needs ear plugs that physically plug into the screen. My husband had some he let me use as I only had blue tooth type. The stewards gave out some headphones to some, but when my neighbor asked for some, the steward said no. So maybe they ran out? Idk. Bring the old kind of headphones or earbuds if you want entertainment in case this is the type of entertainment offered. We had a very tight connection in Miami. 43 minutes. The other economy passengers allowed us to get ahead of them because I asked if we could since we were near boarding time for our next flight and 35 gates away. They were extremely kind. First class wasn’t going to allow us to pass through. We did make the next flight. Our baggage didn’t, but they were delivered to us the next day and we were prepared with essentials in our carry on packs.

We departed early and arrived early The plane was clean and the crew was incredibly efficient another positive experience with American airlines for me.

Flight left on time. Captain provided relevant announcements. We had to wait 45 minutes to desembark due to the ramp closed because of lightening.

Excellent plane, 787. Very good seat and additional stuff they provide. Good food. Very good staff.

Excellent except WiFi is a Must on Biz class 10 hour flight ! Didn’t work entire flight. SW doesn’t do that.

Plane delayed due to weather. Plane boarded, then told to unboard due to a maintenance issue.

Was all good.l including a sofdrink. AA improved significantly. There was no entertainment.

Horrible almost missed my flight because my 1st flight was delayed. Airline crew is so unprofessional. The people on the plane do whatever they want kids running screaming. Will never fly this airline again Suitcases never arrived

Provided a good service and I will use it again. Thanks,

Boarding was not well coordinated. I asked twice at the Level check-in area about the MIA flight. At no point did they say the check-in would be at another counter. Fortunately, another passenger was equally confused and got the REAL story from the airport’s info center. Further, my minor child was tagged “SSSS” on their boarding pass. Level should have notified TSA about him being a minor. Instead, the entire family went through the SSSS process, not just our son. When his name was called out at the gate, it was announced in Spanish. No English announcement was made. The food on board was bearable. The crew was adequate, despite not being Level/Iberia crew (Level contracted out our flight to “World2Fly Airlines” - a company I have never heard of!). The onboard entertainment was very limited. They did not even offer a flight tracker option. Nor were music selections offered. Like TAP and Aer Lingus, I will think twice before booking Level ever again.

Excellent! Outstanding customer service, the best service I have received. Food was served, dinner, snacks, beverages, crew was there to greet you. 10/10

The flight staff was excellent, one of the best I've had. Food and wine was very good and seats very comfortable. Luggage came out pretty quickly too considering the number of passengers. Also, excellent internet. The only thing that could have been improved on was the choice of movies -- kind of limited and not great selections.

Seats are too tight. Small space for long flights very inconvenient.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

Great seat in premium economy, great food and drinks throughout lots of in flight entertainment. 1 hour 40 min delayed flying out , 2 1/2 hour wait at passport control in tampa

Have travelled business class with other airlines who profess to be the best in the world. They can however not beat the service and comfort that BA provide.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

They removed our booking without telling us. Cost us thousands to book last minute

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

Why does a reputable airline like BA allow a miserable domestic airline like AA to operate its flights? There is no comparison between the two

Delayed flight due to lack of crew caused me to miss my connection

Lost my luggage in London Was double charged for luggage
