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

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.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

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!!!

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.

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 delayed because of ground crew, not because the plane wasn’t ready to go. The food was better than usual!

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

It was fine. The flight attendant appeared to be in a bad mood but everything was fine.

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

I was lucky to sit in a seat with legroom in economy . The airplane felt like it was 100 years old, seats were very basic, barely reclined. Food was alright , staff was ok but not the friendliest. But all in all ok trip, perfectly on time

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

Left late after one day delay. Even after we were called to board we stood in line for 30 minutes. Seemed disorganized.

It’s a service to take you from one point to another. No frills. You want it, you take it. It’s upon you to bring food, reading material, games to play, movies to watch, etc. The wifi onboard never works - so you cannot even listen to any podcasts, music, or get updated news feeds. The toilet is a mess, and a four flight does not need any hygienic interventions when people either splatter their pee all over the seats or on the floor. It’s a monopolized service and so smile and bear it.

Great flight. WiFi worked great and the crew was awesome.

Your food is AWEFUL! For Premium Economy this was the WORST FOOD EVER - salad and tomatoes were all spoiled, "chicken" was awful and burnt. This is the WORST FOOD of ANY AIRLINE!!!!!!!!!!!!!!! horrible

I didn't use the entertainment feature. I can't fault that. That was my choice. I could have opted for a bigger seat. Again, my choice. The crew was excellent on all of my flights. I don't really fault the food choices. (I'm one that's grateful to eat). All of the flights left on time or arrived early or on time. Grateful for the assistance that I received when checking my bag at Heathrow. (It was early...hard to think)! I hadn't flown in 17 years. I would consider choosing Air Canada again in the future.

No service in the main cabin whatsoever! I finally ask for water and was requested to get out of my seat and come back to the flight attendants if I wanted water. 3 hour flight, some bumps, but seat belt sign off for about half the flight.

Always have no issues with air canada great staff and food just all around good air line my luggage however was 5 hours late and on another flight and I requested a wheel chair because of arthritis in my lower back and fake hip walking the distance in airport killed me no one showed up for me with requested wheel chair but ....in life stuff happens ..... still a good airline and good people

First time customer, like your airline very much would fly with you again.

Boarding was terrible. We paid for business class tickets, which would give us “Zone 1” boarding. This should happen before the zones for premium economy and economy passengers start to board. However, the gate agents at Heathrow only had “Zone 1” boarding for about 45 seconds before moving on to allowe “Zone 2” and “Zone 3” to start boarding. We still weren’t through the line to board and many passengers from zones 2 & 3 pushed ahead of us to board (it was a completely full flight). When we finally did get on the plane, there were no overhead storage compartments for rows one or two in business. Apparently this is the way that Boeing 787 planes are designed, which is frustrating to pay thousands more dollars for a ticket and then find out that there is no space to store your carry on. Finally, we got food poisoning from the sandwiches and scones with clotted cream that were served in business class. Barely was able to get home to our condo in Toronto after the flight before suffering from vomiting and diarrhea. What was supposed to be a splurge on the end of our vacation in business class instead turned into a nightmare and the absolute worst way to end a trip.

Lines at gate boarding is messy. It spills into traffic which causes other travelers to snake around the boarding passengers. Need better traffic control.

Food is terrible....... need better snacks, too. Crew was lukewarm.

It was a fantastic flight, the refreshments were just great but there was no WiFi , it makes my rating for air canada drop

Flight was delayed over one hour because there was no pilot

The crew assigned did not start on time due to delays on having a person call off sick and later having a person not wanting to stay on cancun. No screens and also no beverages provided delay for 2 h 15 min

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.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

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 took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

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
