Food was the worst I’ve had on a VA flight. Normally it’s a lot better

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

These are one of the older seat arrangements facing away from the windows! Not particularly convenient sets. No storage spaces. NO COAT HANGING HOOKS. Inconvenient business class seat compared to any other airlines of similar class. Staff are excellent! Extremely professional, friendly. Food is good too.

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Great crew - old style upper class seats on the older fleet now feels dated

Premium economy more comfortable than economy, but not by much. Did was awful, do not try the omelette. Flight crew were helpful. Flight was delayed by over an hour. Overall but bad, arrived safely and thank God.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

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

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

flight cancelled after 2 delays. left us sitting in JFK at 1am. no customer service to assist rebooking.

To not have food or proper snacks on a 5 hour flight was the worst.

Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.

It would have been nice if they had offered more than one set of snacks

Ground crew gave me interference about carrying a laptop and a small shoulder bag, even though I told them I traveled with them all the time. I then placed my laptop bag in my carryon and took out a medical device, and ground crew still tried to give interference. I had to remind them that medical devices don't count towards luggage limits. It was quite annoying and unne

Flight was delayed several 3 hours - no reason was given and no communication what so ever.

The gate and ground staff were excellent, friendly, went out of their way to acknowledge my Mosaic status. The plane was an older Airbus, so the seats were a little worn. The in flight attendant was not very nice, and seemed to be annoyed to be at work or be on this flight. Flight was fast and we landed early and pilots kept us informed.

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

No meals included on this long international flight. Most airlines will offer you a meal when flying internationally. Not Icelandair. Your included choices are water and coffee. Poor customer service. The airport was also very confusing.

I flew Icelandair with my partner from Prague to the US. Overall flight time was around 12 hours, with a connecting flight in Iceland. I have flown internationally for years and with multiple airlines. Every airline serves you a meal when traveling internationally. Icelandair not only did not offer an inclusive meal, but they did not even offer a snack. The only things they served over our long flight was water and coffee. Ridiculous! Never again will I fly with Icelandair.

Best smelling onboard bathrooms ever. Even after use the whole flight. Biggest overhead bins. Most legroom in economy class. Great Icelandiic music. Really nice staff. Icelandair is awesome! (Don’t fly Air Canada! During the strike they lied about no flights available (I booked this flight myself) and hid the process to get money back on their website by obscuring menu titles, then made it difficult and time consuming to fill out. I’m Canadian. Don’t trust Air Canada!

It was good. The air plane is clean and staff were friendly.

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

Boarded with no problems. Sat on the tarmac for an hour before taking off. We were the last ones on our connecting flight. Didn't think we were going to make it. Our flight to Iceland was similarly delayed. When we've flown other airlines, pilots have tried to make up time while in the air. This doesn't seem to be something that Icelandair does. We made all of our flights, but it was stressful and we didn't think it was going to happen based on the time we arrived.

Great experience on Icelandair flight from Newark to Amsterdam by way of Reykjavík. Courteous and professional staff. Food was solid. Service - outstanding. Cabin was a little warm.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

It was chaotic. It was overbooked so we didn't have seats until the end but they turned out to be good seats. The gate was at the end of the airport. We had to get busses to the tarmac and board. It just seemed chaotic. Flight was OK. Food was not so good. Lufthansa used to be such a great airline and now as it's with everything else: If you have money you get comforts but if you don't then you end up below deck with the rest of the cattle.

Welp - they boarded us appropriately...then had us sit on the plane for over two hours before cancelling the flight...which meant another night in Munich. I probably had it a little better than most as over 500 people had to be accommodated/re-booked etc. The next day I boarded the same flight (for which I had now been ticketed 3 straight days) and - with "only" an hour delay, managed to finally get home over 2 days later than scheduled. I haven't flown Lufthansa to Europe in years...and I won't be looking to do so again in the future. To be clear, though, the people I interacted with - flight crew, Service Center, check-in were all professional and courteous - management is clearly to blame for their lack of communication and unpreparedness for when things go wrong.

It was a short flight, everything was good with it.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Seat very cramped, could not recline. No cheese with meal. Staff very helpful.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Boarding was poor. Why are first class passengers not boarded first?! Bus to the plane and then held on a packed bus because we were waiting for people on the bus before to finish boarding. Seat belt on the fist clas seat is very uncomfortable, cutting into your neck. Other than that crew, seating and food were all excellent. Entertainment, as usual - rubbish.

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.

We had a pretty good experience. Enjoyed both the flights. Crew was very good and helpful.

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.
