Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!
No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.
We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.
First, Delta needs more flights to/from Miami. Second, a 1000pm leaving at 1230pm is unacceptable from their biggest airport world hub. Another aircraft could have been used such as the aircraft scheduled to be used in the morning for that exact same route. Yes, I did get me there but the lack of sleep the next day didn't help me enjoy my entire trip since I was busy with activities during the weekend. This can be and is expected from Spirit (going bankrupt) and Frontier (despite they're nickel and dimers). But from Delta's World Hub? That's totally unacceptable!
This flight was straightforward and without difficulty. Service was OK, but I continue to be underwhelmed by level of attention given to Sky Priority passengers.
It would’ve been nice for all that money to have a more substantial snack for free. I remember once upon a time getting a very nice turkey sandwich with Swiss cheese on whole wheat bread for no charge along with a drink. I guess those days are gone. it’s a little insulting being given a cookie or a bag of baked chips Going forward I’ll just bring my own.
Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.
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.
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
Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.
It all went very well, except for the ramp coordination upon landing in Boston. That, however, was resolved in fairly short order.
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.
The ride share experience in JFK is terrible. After traveling on a flight, then you need to take a subway to the last stop to get an uber or lyft. Unacceptable. Bad job JetBlue for permitting JFK and Port Authority to do this to your passengers.
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
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
