The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

The flight was delayed because they closed several flight ways because of air shows, fire works, etc.

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.

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

A special shout-out to one of the check-in staff at DUB yesterday noon. We had to use the "Closing Flights" counter and we met, hands down, the most efficient person - able to resolve several issues in the matter of minutes, while remaining polite and calming everyone down. Great job, Aer Lingus!

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.

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.

Quick flight. No time to stress over it. Over before it begins.

Very good, boarded and took off on time and landed early

Delayed boarding because a flight attendant couldn't find the gate...sat on the plane for over an hour at the gate because AA couldn't get one of the planes behind us to move

Boarding was atrocious. Completely unorganized bedlam. Could not understand the person announcing. The PA system sounded like Charlie Brown's parents.

American Airlines, the airline that you can depend on great customer service. Decent fares, friendly staff, great customer service

It was awful. My first flight was delayed and as a consequence I lost my second flight to Greensboro. I did not know what to do so I rebook myself a flight to Charlotte . It was very inconvenient I not to have anybody form corporate assisting me either from PwC or from kayak . It is a very disappointing experience that American did not wait 1 minute or told me to rebook before making the first flight

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

Horrible experience, delays after delays. A flight that should arrive 11:50pm just landed past 1 am, and another 30min waiting for the baggage to come out. Very disappointing.

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.

There was confusion over the electric wheelchair. Though it was categorized and double checked at checking the gate seemed confused by the chair.

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.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

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
