I love this company for comfort, cleanliness on board the liner, excellent food, very good selection of films in Russian. Looked with pleasure. And the main friendly conductors who work smoothly and with the soul.

American Airlines told me that I have 3 other flights in which I did not book! They told me to check with you kayak - cheap flights, my travel agent. Upon calling the person told me “ not to worry “ about these flights in my name?!?!? I never booked any of these other flights. I will not ever use this site again because of putting flights in my name that I didn’t book.

Business class should have free wi-fi. Food was horrible

Will never fly American Airlines business class again. Medicore service and very old aircraft.

Staff went above and beyond with their care for us. Flight attendants were very attentive to our needs. Food seemed too rich and too salty. Flight was fine, even with turbulence at points.

It all went very smoothly, love the new planes and cabin crew upbeat and friendly Food ok, but that is the hardest part of it all

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.

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

The staff on the flight were utterly brilliant; there was a young man who was particularly exceptional. Boarding was quick and seamless, and service was great! Seats were fab, as was the entertainment and its ease of access

i’m The staff on my flight were amazing as always, beautiful professional staff, they do amazing job. the food ? room for improvement

The agents at the boarding desk were not very helpful, however the hostesses on board the flight were great, the food was ok, and there were lots for choices for entertainment. I was stuck in an middle row seat which was a pain on a full flight, but otherwise the flight was great.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Still some confusion about my baggage which was disconcerting. It was nice that there was extra space on the flight for comfort reasons. Staff very friendly

Everything was smooth and the meal was delicious. I really appreciated that Aer Lingus still offers complimentary beverages, food, luggage and headphones. It was nice that the main meal also featured some items typical to Ireland including the wheaten bread and Kerrygold butter. I generally found the flight a quite relaxing and enjoyable experience.

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.

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

Wheel Chair Access sucked. I had a guy from Bangaldesh drop me off without taking me to the gate

comfy and spacious seats for premium economy, nice flight attendants. only problem was the wifi did not work, and my entertainment screen was locked in Arabic language and all kids shows with no way of seemingly changing it. but the flight was fine and I arrived with no issues

It was hot. Need more A/C blowing with more pressure from the overhead vents.

Although it was a smaller plane, the flight was quick and uneventful.

My wife and I caught horrible sinus infections while flying from Athens to Philadelphia

Cabin was bone dry, no humidity whatsoever, and pretty warm; and beverage service didn't start for at least an hour. I had to go to the back for water and the FAs tried telling me it was always this way for all Miami flights, which is complete nonsense. Avoid the MAX8 like the plague.

Flight was 2+ hours delayed and they “misplaced” all 3 of our checked-in bags.

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

Good. Staff was great. The Naples Airport was the worst part of the experience.

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.
