Finnair was ok. But some things were pretty bad: 1. Crew was not friendly, especially a crew member named, Maria. She woke me up while I was deep asleep by force just to let me know that 2 people can’t be on the same seat (my toddler and me) for sleeping. 2. There was no vegetarian option in the menu so I had to eat bread for one meal 3. They didn’t have an option for child meal

The food was delicious. There has been a major improvement here in the last few years. Excellent, friendly service. An enjoyable experience.

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.

I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

We traveled with my 90 year old mother and she was well cared for by everyone from the wheelchair attendant to crew. Greatly appreciated!

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

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! 🥰

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.

Communication not good, too many changes. Three flights were cancelled due to weather and the options were not acceptable. I had to cancel my Canada portion of the trip.

On time and stellar premium class service. Not liking non LCD display in seat backs - miss the convenience of not using your own device.

Very long delay at PHL. The old section of terminal F is a disgrace. Take-off was 3.5 hrs late. It was not just the bad weather, but also too many jets occupying too few slots, a very PHL-based problem.,

My luggage is missing. I haven’t received it. No one seems to know how I can find it

Nothing with the flight. It was good. Crew as very helpful especially fist class flight attendant.

Everything is poor, 1st of all American Air should fix the flight schedule, I never reach my destination ever on time,

Flying on this airline is nothing short of a full blown circus clown show. It is so mismanaged it should not be in business as there is no way it can be safe as badly as it is managed. It is 100% about money and customers be damned. On a recent return from my mother’s funeral, my only available choice from IND to PWM was American, which I hesitantly booked as I rarely fly them for many of the following reasons and never will again. I was booked IND-PHL-PWM totaling about six hours. The flight was cancelled due to NE weather. They rebooked me on a two stop flight IND-DFW (Yes DALLAS)-PHL-PWM, still all on the same day. After arriving in DFW, they continually delayed the DFW-PHL flight due to maintenance issues on the arriving flight. Finally it was delayed to the point that my PHL-PWM connection was no longer possible. They then rebooked me thru LGA with the short flight the NEXT DAY to PWM and offered to put me up for the night in NYC (or so I assumed). The flight DFW-LGA was then delayed so much that I asked to be put in an earlier flight with a lessor delay. Throughout this day chats with their AI assistant were useless as were subsequent chats supposedly with a real person(?). Only one customer service agent in DFW was actually helpful and appeared to care. Upon arrival at LGA post midnight, they issued me car and hotel vouchers in Trenton NEW JERSEY at a very old Howard Johnsons ONE HALF HOUR from LGA. The hotel was an $85, 1.5 rated hotel in a very sketchy area of NJ that I would have never voluntarily booked. As I prepared to catch the car back to LGA the next morning I received a text that my flight was cancelled. TWICE IN TWO DAYS. I went to LGA hoping to have AA book me on an earlier Delta flight. The full service line was at least 200 people deep, so I tried to reach a real person agent by phone. After 1/2 hours on hold I gave up and waited for my later LGA-PWM flight. It actually started boarding on-time, but only shortly after announced a maintenance hold. We were told it was nothing serious, just an adjustment to the Captains seat. Only one update was given while we waited 1.5+ hours for a “SEAT ADJUSTMENT”. During that time at least three others flights in my area announced that they were overbooked and were taking volunteers before bumping people. Another flight to ORD announced a gate change and less than five minutes after announced that they were really not changing and announced for everyone to return to that gate. Can’t forget to mention that on all of these planes the WiFi only worked on two.🤡🤡

Pilot main message was to "be nice to her crew". Crew only instructed passenger to "move out of the aisles" rather than helping passengers place their luggage. Some passengers needed to exit early to make their connections yet cleaning crews rushed onboard to make their way past rushing outgoing passengers. AA needs better protocols and better customer service for the price paid for trips.

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

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

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.

Flight reservation was canceled withou notice had to spend the night in the airport

OK. Needed more information on baggage details with different airlines and airport baggage pickup Also, it appeared they offered free WiFi on their info publications but none did.

It was pretty decent mostly cause I have leg room.

Thanks to a delay of an hour of my flight to Philadelphia on American Airlines I missed my connecting flight to Amsterdam. On arrival at Philadelphia he crew on the delayed flight did not ask the passengers to let connecting passengers get off first and I arrived a few minutes after boarding was closed at the original time for the flight to AMS, this despite the fact that I had received a message from American Airlines that departure was delayed by 25 minutes. Overall very poor service, no effort from the part of American Airlines to accommodate the passenger, just rebook the flight for the next day.

I liked my seats on the return trip. Didn't like having to pay for luggage on an international flight. Also didn't like that it was on American airlines and not British Airways. I specifically selected a BA flight to experience that airline.

Somone switched seats to sit near friend causing us to be disconnected (3) business class. Very disappointed. Staff did nothing.

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

Besides having a LONG layover in Philadelphia to begin with, our flight was delayed and left late. We spent 7 hours in the Philadelphia airport after being in the air 7 hours from Portugal to Philly. It turned into a 24 hour day of travel which was exhausting. I know you can't help weather but our layover was difficult as my husband is handicapped. The staff was EXTREMELY helpful with his wheelchair tho!!

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

The plane was known to be late in advance of takeoff. My guess is that it was known to be late at 11am or 5 hours before scheduled takeoff time. We were late to leave and with a wheelchair and the a cart, we only made it to gate. We raced! Inside plane, all was great
