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 .

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 .

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.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

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 for a fantastic friendly nice we came round and check we need anything else to eat or drink

We originally had a window seat. Our seats were changed to the center isle between 2 bathrooms. This was a red eye flight and we were traveling with an infant. Due to the light from the bathroom doors opening and closing throughout the night our infant would not sleep and cried the whole night which kept us awake and everyone around us. It was a very unpleasant experience for everyone trying to sleep.

Generally good. The crew is excellent. The food could be better.

Excellent apart from transport to actual plane 10 minutes from the actual gate , walking out in the tarmac in the rain and having to climb stairs to enter while holding luggage.

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

No bording was given for next trip on same carrier, food was very moderate.

Lost luggage, 2 bags were badly damaged and one of the bags came open.

A couple of minor delays in boarding but very professional and efficient staff.

My seat was so uncomfortable, and the headrest was broken. Very very disappointing for the price I paid.

Even though my seat is a paid seat, I was told to give up my seat to a passenger. I tried to ask the CA to negotiate, and when I spoke in Japanese, the CA fled. I had to find a Japanese CA and ask them to deal with it. . After takeoff, I spilled my coffee, and when I asked the flight attendant for a towel, she told me to wipe it off with a wet tissue. My clothes got wet, so I asked CA for an extra blanket, but I had to wait for an hour.

Cons: "Not to have 2 distressed cats on board meowing non stop for 10 hours."
Pros: "The crew is nice"
Cons: "No respect of distancing the seats ; all the seats were occupied. No wifi"

Super unproffesional flight . Flight attendants were unproffesional. I could hear them gossiping about theor boyfriends the whole trip

The connecting flight lay over was 4.00 hours, the gate agent booked me on the next flight which was about to depart at no extra cost.

The ticket price was reasonable, food was okay, not the best. I would use the service again.

Actually the flight was on time. New plane, food was okay but not great.

Old plane, hard seats, 1.30 hours delay, while seating on the plane waiting for departure.

Great boarding. Everything was on time. Plane was a bit old and the crew could have provided better drink service.

Crew was pleasant. Aircraft was very dated and uncomfortable for our nearly 4 hour flight. We were in row 17 and they ran out of purchasable food by the time they got to us.

Lisbon, make sure to get food , coffee prior to going to boarding gates as there is no food being served after. Only vending machines. A lot of check points to get to the boarding gates. Not enough seating for passengers waiting to board. Crew was very courteous and kind.

We could not check in early, I think because we purchases through a third party, therefore once we got to the airport, no seats together, and only middle seats. Will never do that again

Once we got through the long line at security, everything was very good from boarding to exiting the place. The flight crew was very friendly. What Air Transat could do much better is to put us through to TSA Pre-Check since my wife and I are Nexus members. We have never enjoyed this privilege with Air Transat, but, we always get this with Air Canada at the FLL airport. So, this is possible to do.

It was a domestic flight so the food was not included. But we had not even a little snack and by the end of the flight they were coming around serving water.

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

Seats could be more comfortable and food can be better and price was too high

Lost my bag. My first ever flight with them that they forced me to gate check my bag on, due to them having a 30 year old plane with small carry on bins, and they lost my bag. Never again.

The seats are so close together and when the person in front of you reclines the back of their seat you have even less room. It's quite uncomfortable.

The trip was fine and uneventful. The seat in business class was very uncomfortable which was disappointing given the extra cost. It was spacious but it felt like I was sitting on metal bars. The food in business class wasn't very good. The flight was ahead of time, the staff was professional and courteous and our luggage arrived safely.

Got the email to check in but when I tried to check in it said "cannot connect to server", so checked in at the desk.

For me was not enough water. + 200 ml would be perfect… Generally it was good.

Again we were late leaving Austin , there was no tv screen for the 3.5 hr flight, the pizza I bought was kinda bland

Main chicken dish was okay but the beef snack was not. Restrooms in the back were clean and uncrowded in spite of the full plane, although our friend in the section forward did not find them the same there. Delayed one hour on tarmac before we could leave Rome.

We were helped whenever needed and had a pleasant flight.

Air Canada from Edmonton to Toronto was disappointing but Lufthansa from Toronto to Frankfurt was excellent.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

bad seats, meager food quantity. bread not fresh. Hollywood films lack entertainment.

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

Boarding is as always an issue. Slow and long boarding time.

I paid a lot of money for seat selection and was miserable for flight duration
