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.

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!

Flight crew was very cold and stood around a lot talking to each other.

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.

On time, only a little turbulence, very competent and caring attendants. Clear information.

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

On a four hour delayed flight now on seats back end of the plane instead front-

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

Rudest flight attendants ever, waited over 20 for light to be answered and it never was then tried to flag down an attendant who said someone else would come, just needed water to take some medicine Food bad

I had the best flight crew I have ever experienced in all my years flying with AA. I would specially like to thank Till Tatum/96038 for her kindness professionalism and outstanding service! My son turned 8 years old one day before our flight and she went out of her way to make him feel so special. We will never forget this flight! The whole crew made a special card for Frankie’s bday and it really touched our hearts. He will never forget it and neither will we! Thank you with all our hearts! We hope to be on more flights with Till Tatum and this amazing crew.

Hydraulic leak caused the flight to be cancelled. Auto system scheduled us on a 3 am flight. Wevhsedvrebook on the app and hit schedules later in the afternoon. Our luggage per gate and ticket agent would be rescanned and put in our new flight. Did not happen. Our luggage stayed in hsv. Baggage claim in wash dc unable to help. We filed a claim. Several emails about our luggage were in conflict with one another. Called as baggage and was on hold 30 minutes. Oscar said one of 2 was out fir delivery then cancelled. About 45 minutes later both pieces were delivered. Their system is suspect

My entertainment unit kept locking up and had to be restarted multiple times. Also those commercials for Budapest and Ralph Laureen. Come on those were stuff only those who can afford the outrageous fees of first and business class would be interested in.. And the fact you have no military discount is not good either,

I was not clear if food was offered or not.

Flight cancelled. Twice. And no communication. No gate agent. Went past boarding time and had to go and see email from AA. Airport communication was bad

I love the e fact that the staff communicated swiftly when my flight was delayed and gate number changed

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.

Delayed and horrible communication and sat on flight for an hour before taking off

I was a Wheelchair Assist’ passenger on a London Heathrow to PHL flight yesterday. The process of getting me and my carry-on bag from the ticket counter to the gate was not good at all. It was the worst in my 5 years of experience using this service offered by American. The Philadelphia ‘Wheelchair Assist’ service was, and always has been Excellent! Not so at Heathrow. I was handed off to three different wheelchair drivers; had to sit in a very dingy holding area for 30 minutes while waiting for our gate change announcement; got crammed into a overloaded service vehicle to take me from the holding area to the gate ; was dumped at the end of the line of already-boarding passengers with my heavy carryon and no one helped me up the ramp way at the gate to board the plane. Overall it was a miserable experience!
