Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Late, dirty cabin, charging ports broken, uncomfortable, no tomato juice, barely edible food

Flight on time, landed well ahead of schedule. Attendants were excellent and responsive

The crew was friendly, and the flight landed on time

Rude Iberia security crew at the Madrid terminal. No Iberia officials to be found to redress complaints at the gate. No supervisors. Nothing for processing upgrades at the gate Iberia app did not work to let me upgrade my options to higher classes. No water was offered on a hot day in Madrid. Madrid airport air conditioning was so weak that people were sweating. Never book on any airlines that codeshare with Iberia.

Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

It was okay. The airplane was a little smaller than a flight from Thailand to Helsinki.

Wish that everyone would board the back of the plane first. Also let kids on first. The gate wasn’t open at arrival and we waited 45 minutes to takeoff. They made up for time in the air.

This was an absolutely exceptional flight. The flight attendants were extremely attentive and very friendly. They seemed to go out of their way to make us comfortable and to make sure that we had everything we needed., We were in business and were very happy with the size and the details for our pods. We would definitely recommend Finnair and will definitely be flying with them again.

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!

We missed that flight, and I am hoping that we will got the refund. It was very confusing to figure out about Aer Lingus operated by American Airlines. Then we bought another more expensive ticket to travel.

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!

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

My luggage never made it, I booked business class only to find out I’m sitting in the back. Very disappointed with the reservation

We were treated politely and the crew was nice. Again no one knew why there was a delay. Food was hot and a lot was offered but bad in taste. Seats weren’t the worst but for a long flight your legs ache from it. Entertainment was old not very interactive

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

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 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!

My flight times changed 4 times since I originally booked the flight. The last time being the day of flight - a 2 hour delay. This meant instead of getting into IAH at 9:30p, I got in at 2:30a. This was very disappointing!!!

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

WiFi didn’t work for me. as headphones didn’t work either.

Food was terrible. Going to Italy I gave benefit of the doubt however returning to the USA was no better. Rolls were frozen. Butter was frozen. Quality of entree poor

Cabin crew friendlier, they weren't weren't unfriendly, but simply professional and not more

The crew on AA international flights in my experience are generally lazy, rude, and inefficient. These guys did not disappoint.

The plane sat on the tarmac for 2 hours, it was terrible. No drink service during the flight. Terrible

Comfortable seat Attentive cabin crew Asian vegetarian meal very good Not enough drinks were offered during flight No ice cream Snack offered before landing not good very unpleasant taste no choices

This flight was rebooked from a missed connection 3 days before due to connecting flight cancelation. We had upgraded on our original flight but were assigned coach seats on this flight. BA could do nothing to upgrade us due to this flight being "overbooked" and "busy". We should have been rebooked in upgraded seats. Now we have to apply for a refund.

Plane arrived late to gate, staff at Philadelphia had no sense of urgency to get people on the plane. Boarding took 15 min longer than it should have because despite 4 staff working at the gate, only one was scanning tickets while the others sat talking to each other.

When I bought the ticket, right away I got a problem, I had to cancel. Unfortunately never ever I will use kayak or Iberia again. When trying to cancel kayak told me to talk directly with the airline, the airline talked to me through whatsap and told me to deal through kayak. Both of u never took responsibility in helping me out. You kayak did not want to deal with me. I called my credit card and now we r disputing the charge bc u have a pathetic customer service.

Ability to select seating would be nice. We were family of three and they had us seated back to back and one of us on the other side of the plane??? That is pretty goofy. Especially when tickets were placed two months in advance.

How to get an aisle seat without paying extra? The young lady next to me was assigned the seat.
