Our flight from SFO to MSP was right on time on 11/15/2025. No delays. As we approached MSP at about 8 pm, we circled in the air until 8:40 pm so I don't call that efficient for MSP. I think the captain should announce the delay and why. (as if we all don't know that we are just circling around the area, slowing down, speeding up, slowing down.) Thank you. Marilyn Fischer

Service in business class was not impressive. I ordered coffee with dinner and then watched other people get 2 refills before I got my 1 cup of coffee, and only after I pressed the attendant button overhead. Furthermore, the seats in the forward cabin need maintenance on this 737-800: the upholstery is detaching from the seat frame, at least on the backs of seats 1C, 1D.
Plenty of leg room, temperature was great and staff was excellent. Would do it more often.
The ticket agents in West Palm Beach on Friday afternoon Nov. 7th were incredible in getting us on an earlier plane to Atlanta during the government shutdown. Had the taken our original flight we would have missed our connection. She did this on her own, We didn't even have to ask, and she did it all with a smile and showing genuine concern that we would be taken care of. We are very grateful and thankful. We fly often, and now we will be sure to fly Delta.
Flight delayed then cancelled. Misplaced luggage. Still do not have. Rented car 1100 mile drive. I had to buy some overnight Hotels clothes toiletries gas food at my expense. Still not home. Not sure where luggage is. Over 4 hours on hold to Felta
I truly love flying with Delta. They have always treated me with the upmost respect
Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.
Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.
Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.
They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.
Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…
Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.
Our flight crew were terrific. And they handle a difficult passenger with finesse.
Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.
3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account
I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.
I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.
It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.
Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price
It was an OK flight with below mediocre service by their flight attendants
NOTE. Aer Lingus does not accept American Express. I was denied boarding because I could not pay the fee for my oversized bag. I did not have another credit or debit card. Moreover, at CDG, I needed to check my bag at one location, go to another location to check my oversized bag and a THIRD location to pay for my oversized bag. Hence, once I was denied boarding, my bags were already en route to the plane. To retrieve them I needed to go to a FOURTH location in another part of the terminal. Last, Aer Lingus will not reimburse me for any portion of my ticket. I lost $1000 bc Aer Lingus doesn’t accept American Express at the CDG counter even though I paid for my ticket through the Kayak link with Amex. Kayak should remedy this situation if they want to continue to partner with Aer Lingus.
The biking process was confusing and I was called for a seat assignment from I number I repeatedly though was spam, but the flight itself was great
It was poor overall. They cancelled our flight and changed it without notifying us. So we incurred extra costs by having to book a hotel for our layover. They say it's Kayak/Underpricer's responsibility to reimburse us. But Kayak/Underpricer have said it's Aer Lingus' responsibility because they are the ones with our 'booking information.' I find this situation confusing and unacceptable.
My experience with Aer Lingus was not too good. First, because of the last minute delayed flight from Amsterdam to Dublin we almost missed our flight from Dublin to Philadelphia. Secondly, the flight from Dublin to Philadelphia had very uncomfortable seats especially it was a very long flight. My buttocks were constantly in pain for sitting on these seats for this long. Lastly, the service in the plane was also slow. I asked for a second cup of water and the hostess told me he'll be right back with that where it took him over an hour to come back with water. It was warm in the plane and I was very thirsty. Overall this airline needs much improvement in their services.
Staff was generally friendly and helpful. Attendants collecting trash were somewhat inattentive though.
This flight left about 45 minutes late, and arrived about 45 minutes late, which was enough to make us miss our next flight and trap us in Dublin for 24 hours!!
I think the extra charges for seating with no added advantage and the added charges for baggage are excessive compared to other airlines.
I had zero issues with the flight. I did have issues with the staff at the airport. We missed out flight due to a delay with another airline. Talking to the staff and trying to get a new flight arranged was challenging. One guy was able to try to help us and got us on a new flight, but other staff was dismissive and clearly let us know it wasn’t their problem. All I kept thinking was… this is why air lingus has such a poor customer service reputation. I will be avoiding this airline in the future.
Food was just okay. Was surprised initially when was charged for a cup of tea when they first came through cabin for beverages. I’ve had far better long distance flights ( take some tips from Swiss airlines)
The boarding process was not good. From check-in, there was only one desk for check-in, which made for a very long line. I asked to print out my boarding pass for the next leg of my trip, also via Aer Lingus, and they said they couldn't. I was unable to do this on the app or online, either. Many fellow passengers I spoke to had the same issue. Because the plane was delayed taking off by 90 minutes, everyone had to quickly go to a desk for their next boarding pass which was chaos. Overall it wasn't a smooth or happy experience.
Checking In on JetBlue site was impossible. It hung up on REAL ID. Even my Global Entry did not help. Luckily, on Kayak site it was a breeze. Entire flight the temperature was COLD! Otherwise the crew was great!
The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.
Very pleasant flight attendants. Gate crew rather loud chatting with each other.
Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.
Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.
There was a fowl odour coming from the lavatory the entire flight
Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.
I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).
No internet on a flight over three hours in this age is criminal. Staff inattentive and dismissive
They have the most inexperienced / rude flight staff I’ve encountered
Excellent experience in every way, from ground crew helpfulness, boarding experience, inflight service all the way to modern equipment. My new favorite airline. I wish I could fly with them more often.
For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.
The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.
Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours
Was very good Staff was great. No tv monitors tho. So long flights make it longer
The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.
Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time
have screens on backs of chairs...offer free snacks and water
