Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

8.0 ExcellentDerrick, Jan 2025FLL - EWR

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

No music app working: no economy meal on five hour flight; hour on tarmac at the end waiting for a gate. Flight itself was smooth and easy.

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

The flight was delayed for 4 hours. Once onboard the crew was wonderful.

Overall was excellent. Will definitely us JetBlue in the future.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

Flight was on time arrived at the destination 10min early they kept in touch via email

Food choices were very limited. Taste of the dishes was average.

Maybe add a seat trade app for flyers that didn’t get seats together

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

EVen warmer in the plane it think it was 24+ degrees

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

Fast checkin with the self serve terminal, good communication at the boarding gate.

Very friendly staff. The flight was on time. Need a bit heavy covers/blankets. It can get colder with a thin blanket.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

You cost me my time and did not compensate properly. Gfy.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

All flights were on time! The crew was nice and polite Thank you. Food was awful. They give you terrible pasta or rice dish and make you pay for chicken if you’d like meat. When I asked for water with my tea, they told me, I’d have to pay 3 euros for water. Restrooms were filthy half way through the flight.

The meal offered was fish. I am allergic to fish. When I told her, she just took the box of food back without offering me an alternative.... I had to ask... can I then have a bag of chips? She did give it to me. I am a Euro Bonus gold member. Please just take the time to offer something else. Easy and from a customer service point of view, .... Considerate.

It was ok. Vegan meal was good, however no complimentary alcoholic beverages.

compared to other business class journeys, the hard product is okay..but the service of the staff is underwhelming. They are very senior and seems only to care for the colleagues they upgraded to biz and to themselves , I was not offered food before after 1 1/2 -2 hours, and the menu had one dish and the food was not that. And i could not get the breakfast.. just coffee and a croissant. i have type 1 diabetes .. luckily i had my own food. was low in sugar after sleeping and woke up 55 minutes before landing .. not able to get food anymore !! so bad business experience!

The food service was absolutely rubbish. Very arrogant crew. Does Scandinavian airlines think everyone eats meat??? I paid for my flight but could not eat anything because I am vegetarian!!! I was hungry for 7 hours . I demand for refund! This is absolutely unacceptable!!!! If you want more customers keep an open mind!!! Cater to all meal needs. I have flown many airlines and I never make a special request online never! They always have vegetarian options. SAS has no idea of customer service. Shitty service

LAX to Copenhagen was very nice…business class…great service and comfortable seats…great value…Copehagen to Barcelona…business class was normal coach seating…a little cramped…box meal….good service

Had recurring problems with the touch-screen entertainment system repeatedly making up inputs, resulting in the movies randomly jumping forward and backward. With the lack of proper controls, it was also difficult to get back to where the movie was up to. These phantom inputs were so comprehensive that the system even changed the language setting. Despite a schedule 6.25pm boarding time, it was announced in the Delta lounge at 6.15pm that boarding for the flight had started, so of course everything started to head down. While the gate continued to show a scheduled boarding of 6.25pm, it was 6.32pm before boarding actually started. No, not significantly different, and we ultimately ended up landing well before time (and landing time is arguably more important than exactly when boarding starts). Seat comfort was fine, although only a small nook for personal items, food was satisfying for me, and crew was pleasant.

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

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

Check in and boarding was easy, crew was cheerful. Not much to read or do on the plane and our neighboring passengers were talking loudly so we could not sleep. But overall good. Great coffee.

Flyplay is the only way I travel to Europe. Had a 15 hr layover in Iceland. Normally this would suck, but I regret a car and saw the black sand beaches, several waterfalls and sky lagoon. And finished with lamb at cafe Loki.

did not get the seats we had specially paid for

This is a no frills airline. You cant expect much for the price. Low cost flight, clean, nice staff. That's all I need for the price. If you want more, book with another airline and pay more. For Europe trips, PLAY is the ONLY airline I use

The flights were in time and the bags arrived. well done

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Overall good. I was surprised how easy it was to get from plain to plain in such a short time. Food choices were not so great and quite expensive. Entertainment was ok. Flights were smooth.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

take snacks and food. purchase options in flight are not great

Had a screaming child next to us. Not the airline’s fault but still annoying.
