Nothing special. The crew never went out of their way for anything.
Nothing special. The crew never went out of their way for anything.
Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate
Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.
Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.
The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,
On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.
The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!
I believe that a four-hour trip should have a meal. Delta had none.
Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!
I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.
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.
The food was great and the service and attitude was amazing!!
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
Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.
My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.
The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.
I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!
I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat
It was great. I had never flown on JetBlue before, but would be very happy to fly with them in the future.
Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.
The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.
Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.
My JetBlue experience was nice. The flights ran on time, the aircraft was clean and comfortable, and the flight attendants were attentive. My only issue, which is isolated to the low-cost (budget) option at JetBlue, is that the check in process makes the user feel that they have to buy their seats. The seats offered for purchase are upgrades from the budget seats you get (which are essentially the last seats remaining). The interface should not make it feel like you must purchase a seat.
The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.
I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…
There were mutliple delays. There was inconsistent, delayed, and poor communication regarding the delays.
flight was delayed for hours with no explanation. The plane was a very old aircraft.
Terrible. The test of an airline is how they deal with problems. There is very little to differentiate between airlines. Aer Lingus failed absolutely. They lost one of my bags even though we had more than a 2 hour connection in Dublin. Trying to get it back has been awful. In checking on line I can see that the bag is in Edinburgh and it was supposed to be delivered today. It wasn't. The number we have in the UK doesn't answer. I had to pay for an international call to speak to somebody. All the woman at the call centre could say was be patient wait. I can tell you when it will be delivered nor can I tell you who the courier is.
A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.
Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.
Overall it was good experience and it was my first trip with Aer Lingus. One thing I was embarrassed was that someone occupied my seat so I was asked to use another seat. Due to this unhappy happening I almost missed the connecting flight because the random seat was far from the flight door. Food was fine, I liked the macaroni and cheese with fresh bread.
I was very disappointed that the online sys allowed me to get the boarding pass for the second leg of the trip, when I clearly request it for both flights!
It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.
The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.
The seat pitch was a little tight for me, but I survived. There was a volatile, enraged passenger a couple of rows ahead of me and the cabin crew defused and resolved the situation calmly, quickly, and successfully.
My experience with Aer Lingus was nice, and I would be happy to fly with them again. However, my seat pocket had not been cleaned and had dirty wipes in it. I have flown with Aer Lingus before and do not recall anything like that happening, so presumably this was a one-off kind of thing. For the meal, I asked if there was possibly one without my allergens and the flight attendant gave me the one she thought would be fine. She did not know what allergens were in it, but when I received the meal the allergens were all listed right on the top of the package, so I was confused about why she didn’t know how to check what they were. In future, I will see if it’s possible to request an allergen-free meal ahead of time. But overall, I had a pleasant experience. My experience with Underpricer was very unenjoyable and because of them I do not plan to book through Kayak in the future. I have used Kayak numerous times, but this booking experience was so unpleasant. They called me numerous times and also emailed me to try to get me to select a seat. However, when I had a question later on, I was kept on hold for 20/30 minutes before I finally hung up. I also emailed them but never received a response, which I did not appreciate, especially given their previous frequent calls when they wanted something from me.
We booked a flight from FCO(Rome) with a stop over at DUB(Dublin) going to JFK. Boarding from Rome was kind of chaotic since the airport I guess is very small and we needed to shuttle to the airplane. The gate agent just let everyone and anyone go without using the sections so that took a lot longer than usual boarding. From drinking to JFk boarding was good and organized. Amazingly the flights was very smooth sailing and we’ve flown American big airplane to small companies before. The aircraft’s itself is on the older side, can’t complain tho because the plane ride wa smooth. For a 3 hour plane ride, nothing was complimentary. But for the longer leg of the plane complimentary snacks, meals and drinks were provided which was great. The food wasn’t bad either. I would fly with them again, great price and good service.
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
