Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff were fantastic friendly nice they came round and check we need anything else to eat or drink

they made me check my carryon. There was space in the overhead bins.

The Polaris experience is top notch. From departure lounge to arrival lounge. Everything was top notch. One of the best first class experience

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

EWR terminal C United Club is great. Flight and everything else mediocre

Flight delayed for 2 hours due to a part. The plane sat waiting for boarding for a long time and during final preflight inspection the issue was found. Why not do the preflight inspection sooner if you know the plane is being used?

The crew were really great, but the 4 hour delay in small chunks was the worst.

Very bad , airplain had problem with engines , had to evacuate, had a delay on my trip for almost 4 hours , lost my rental car in london..

All good, useful to have the united app from check in to boarding

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average,

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

Misleading instructions for check in. Although I did virtual check in and was instructed to head to security, once I was at security, they told me to go back to Play ticket counter and get paper tickets. Also, beware that Play doesn’t participate in TSA PreCheck. I didn’t know that, despite entering PreCheck info when I purchased the tickets. I wasted time in the TSA PreCheck line as well. So we had two setbacks at check in.

It's a budget airline, so forewarned is forearmed. Yes, you pay for everything like carry-on, checked baggage, seat selection, but that's becoming the case with major airlines. Bringing your own snacks and entertainment on board is highly recommended. It's no frills, but the crew, the plane and the flight itself was great. If you want pampering go for a larger airline. If you just want to get from A to B in comfort and safety, Play is a great choice.

It is a low cost airline. Staff are courteous. There is no entertainment. Food is purchased.

Upon boarding, the people at the gate were extremely rude, there were no outlets on a 6 hour international flight, there was no entertainment, all food and drink was purchase only (even snacks), and my seat reclining function was fully broken. The only redeeming quality was the flight attendants were extremely nice. This was by far the worst flight I have ever been on in my entire life

I don’t know how international flights can’t have media screens to keep people entertained for the long flight. Ugh.

Typical experience for budget airline. Boarding from KEF required bus transit from the gate to plane, so if you had "priority boarding" it was useless as it was simply a free-for-all when getting off the bus. But still no issues with getting our luggage into overhead bin so not really a problem.

Was very apprehensive about flying Play, but the flight was fine. Nothing special, nothing horrible. Fair price to get from New York to Iceland.

I wasn’t able to check in online the day before or the day of because their web configuration or business model idk. I arrived an hour early and check was closed and there was no one around to speak to and eventually was told there was no possible way to get a digital ticket despite I had no luggage to check and would have easily made it through security to boarding and had to pay for a new ticket for $330 ontop of the $169 I spend for the ticket and then I missed my rental car for $305 because I only arrived at midnight instead of noon that I was originally intended. All booked through kayak. I hope there is some kind of insurance from kayak because this was totally preventable had I not been blocked by play air from getting my check in and plane ticket.

I loved the ability to upgrade my seat which was worth it. The large seat and ability to recline made it comfortable to fall asleep. My only two complaints were entertainment (movie selections were old) and approx 30 mins before landing the crew started to collect the blankets despite the cabin air temperature remaining cold. Maybe wait for passengers to get off the plane before collecting the blankets.

Excellent! Although it stinks to pay extra for leg room and then have no screen option.

Very much dislike: Airline requires check-in at the Airport Airline does not work with TSA PreCheck

Overall a great experience. Only complaint was the movie selection was pretty limited, but that's pretty minor in the grand scheme of things and easy to overcome.

The crew was unfriendly front check-in. The filth in the plane was so disappointing. I could smell dirt and looked up and there was literally dirt that was blowing in through the air. Old food on the seat back tray in front of me so I didn’t use it. No toilet paper in the bathroom and scum/old dirt next to the seats.

No blanket pillow headphones, not even a water or snack makes for a very uncomfortable flight. There are too many extra fees that should be basic and standard included.

There was no communication about the check-in process, even the fact that Norse doesn’t do online check-in! And once we were at the Los Angeles airport (LAX), there was no signage or assistance about where to check in. I kept Googling for 3rd party information until I finally found on the airport website that we had to check in at Terminal 1 and be bussed back to Terminal B, the international terminal. How were we supposed to know that?! Otherwise, the flight itself was comfortable and the attendants were helpful and friendly. I just feel like we were lucky to have managed the check-in and boarding process on our own - why keep it a secret??

The flight was comfortable, smooth, hardly any bumps even though we encountered some jetstream. The onboard entertainment could be jazzed up a little, the TV shows were old ans not much variety. The movies we ok. The staff was pleasant. The Orlando ground crew was excellent, they were pleasantand friendly. My kids and I were seated separately but the Orlando crew was able to reassign us together. The ground crew at Gatwick, UK need some work on attitude, they were not so sociable. All in all wonderful flight to and from England. I will be definitely traveling with Norse again. Ps...Norse need to work on an app for both Android and iOS.

Crew at airport who completed boarding were incredibly and blatantly rude and unhelpful. 0/10 customer service. I was going to upgrade my seat to first class and upon asking, I was met with an awful attitude so I changed my mind.

Boarding was a disaster. 2 hours in line to get boarding passes and we had no luggage to check in. Coffee was $4 so is water. 11 and a half hour’s flight and food was not included. You could purchase the food but it was complete garbage, This is worse than spirit airline. Never again

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.

This was an American Airlines flight. The crew were very unhappy and quite grumpy. Abrupt to the point of being rude. The food was dreadful. Indeed the breakfast was in edible. I will avoid AA at all costs in the future.
