overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

It is usually very pleasant. Good service for the price, international flights are even better

New high end luggage ruined/zippers broken, items missing. All happened on return flight from msp to mso. Do better! Not store bought luggage but high end personalized ogio custom embroidered luggage. Total slap in the face ontop of an extra luggage fee that took me 3 hrs on chat to resolve.

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

Very comfortable flight. Great service, food options, and entertainment options. With Wi-Fi!

On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

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 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.

Did not know that they didn’t have screens for entertainment. I didn’t have headphones so I couldn’t watch anything on my phone.

Gate 461 the worst in LAX Boarding lacks professionalism And as usual, your food sucks.

Bad experience going to DFW with an IT outage then bad on the way back with a nearly 5 hour delay that’s started as maintenance then caused us to wait further due to weather - which would not have happened if we had left on time.

I was stuck in Miami for 24 hours! I waited in a line for 3 hours just for a hotel still at the airport. This was the worst experience I’ve ever had.

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

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
