Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

My American Airlines flight was deleted and you guys never let me know

The entertainment system did not work. And we waited 45 minutes in our seats after we landed before we got to the gate

It was a pleasure definitely going with Iberia on my future travels

Our connecting flight was cancelled and it took us 15 hours to reach our destination.

This has been the worst experiencia I have had traveling overall. More than 3 delays, no one answering questions, no one at the AA counter. No one at customer service and after having to change transportation to airport and spend the night at a hotel paid by me, we were delayed inside of aircraft for more than 2 hours!!! Bad experience!!!

Seats were old and dirty, for a long haul flight you expect to be able to recline and for the av to work properly. Choice for vegans was fruit….

The Virgin Atlantic crew was very good. However, the equipment was OK, the seats were OK, but her bags did not arrive with me. Two bags showed up a day later and I’m still waiting for my third back.

The crew was very good. However, the equipment was a bit dated. Some of the electronics were not working. To top it, three bags didn’t arrive with me. Two of them were delivered a day later. I’m still waiting for the third bag, I was so looking forward to this virgin Atlantic flight, but, I am disappointed.

My only complaint is that the pocket in front of me was ripped and my things, like iPad and airline magazines, kept slipping to the floor.

Flight delayed yet again. Crew apathetic and unhelpful re affect on connecting flight.

I think Virgin is one of the best flying experiences, especially from/to the UK. The staff are so helpful and fun, the food is good, seats comfortable, goof entertainment and great value. Check in and boarding is pretty pain free. I also find that the other passengers are generally so kind and considerate than when I've flown other airlines.

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.

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.

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

The flight itself was fine, but the boarding process was extremely frustrating. There is no one scanning boarding passes - passengers just scan themselves and enter the jetway. By the time my husband and I got on the plane and were halfway to our seats they determined there were too many bags on the plane and everything at that point needed to be checked. This created a lot of unnecessary chaos. They should have alerted people before getting on the plane that they would need to start checking bags instead of waiting until people were already on the plane.

The best flight I’ve had in a while. The plane was like 25% capacity, if that. Smoothest boarding and deplaning process I’ve ever experienced. Wish all flights were this smooth.

Did not enjoy this flight at all. All of my coworkers flew delta and I chose JetBlue because I really value how simple the WiFi and entertainment is and this flight I didn’t get either. Crew staff was unsympathetic to my system not working, everyone I asked for help with was extremely bothered by my request for help.

I like their airplanes because they have plenty of legroom in their seats they always work with me if I have a change of plans on my tickets courteous and I always feel safe flying with them.

I paid for the service of having the right to choose my seat and it was not like that, they put me where they wanted and I explained to one of the staff that they were before boarding and they were very rude. I am traveling with the family and they put us in separate seats.

Little snafu at boarding. Staff communicated with gate poorly. Flight attendant was rude making disembark early. This was an older mint class. Needs an overhaul for sure. Food was good. The male flight attendant was really nice.

My encounter with the entertainment services provided on board was moderate; the functionality of the Wi-Fi connection was either sluggish or nonoperational, while the display screens were antiquated and suffered from poor visibility. On the positive side, the cabin exuded a sense of expansiveness, and the crew exhibited amiable and accommodating behavior throughout the journey.

Everything was great except for some reason crew and ground crew could not figure out how to deal with an electric wheelchair and it delayed us 20-30mins. Was pretty frustrating for passengers and the captain.

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

Service was great, we had bad departure and bad arrival due to weather, but that we cannot control. Hats off to the pilot!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

They canceled our flight and left us stranded to figure it out

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

Pleasant, attentive and efficient flight attendants. Boarding process and seat selection easy. No internet on transatlantic flight. Extremely uncomfortable, rigid seat.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced

Horrible food and uncomfortable plane. One toilet was out of service.

Business class is fantastic! Lie flat seats, great meals, privacy, and lots of nice amenities!
