Top 5 airlines serving from Washington, D.C. to London
they made me check my carryon. There was space in the overhead bins.
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,
Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.
The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.
Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(
You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.
This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.
Always getting updates by email very easy to check in on line. There was plenty of checking in staff to get you all through. It was nice that the flight attendants took time to talk to you and were interested in your holiday.
Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault
Food was very average. And top up drinks offer was absent. For a 11 hour long flight that should be the minimum. The crew didn't want to be there. I understand it was new year day but given they had signed up for it
It was my fault choosing the seat nearest the entrance but it was ok.
It was good, the staff was friendly and it was a typical flight to Europe.
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
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.
As expected for a BA long haul flight in economy - you get what you pay for. Good leg space, in flight entertainment and food and drink provided. Staff on the return flight (overnight) we're a bit brisk and just wanted to get everyone fed and watered before turning the lights down. We're vegetarian so ordered it separately through the booking, although when we were in flight we realised there was a normal and vegetarian option anyway, and we were given vegan. This is fine, however on the return trip we were told there were no more specially ordered meals left, so be aware in case you have specific dietary requirements.
