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 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.

Flight got delayed due to a technical issue, but they were quick to find an alternative airplane.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

The flight was 90 minutes long and the stewardesses were extremely slow. I was in row 16 and they did not serve us drinks until we were descending for landing in a 90 minute flight. Unacceptably slow and at least 10 rows (20 to 31) did not receive any drinks or snacks for the entire duration of the flight because of the slowness of the stewardesses. There is no rationale to delay beverage service to brew coffee for a flight at six p m.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

The main flight was OK but the second flight was chaotic with delays

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

All the British airways staff were very helpful and friendly. Every thing was very smooth running from checking in boarding and arriving 40 minutes early. Which is a brilliant start to your holiday.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

No nice at all, delayed and I lost the connection over xmas

The staff were on the last leg. But they were still very accommodating and polite. They were all very helpful with getting the bags up and getting people to their seats.

Was delayed, did not end up flying to Victoria. Was not offered alternative accomodation or travel. Very dissapointed. Had to pay out of pocket for taxi, ferry, food etc.

The boarding process in Toronto bad as they share space with domestic flights and when those domestic flights come in you are locked out behind closed doors until they are done and then its a mad rush to get your boarding gates and board. This is not so much due to Air Canada but with the GTAA, but Air Canada could use different gates especially early morning in order to prevent such travel angst.

Crew members were very polite and prompt in service. Cooling was very comfortable for a long journey but it's seats were stiff which are uncomfortable for a long travel

Over 4 hour delay in departure. Aircraft and gate changes. Problems loading cargo. It was a mess.

The cabin crew were really good!! Check in etc. was very good. We enjoyed the aisle seats as the plane was small! Couldn’t comment on the food as we didn’t order anything!

It is admissible that we have to pay over price to eat on a 5h flight...

Great. As a tall person the seats are quite cramped.

I am 6'0 and almost no leg room. I am also not a small person, but this was the first time I had a issue with the seat belt. I feel like they should be made a tad bit bigger.

Notice to check in on my phone. When I tried it kept sending me to there employment website Larger gentleman in window seat over lapped into mine Forcing me to sit sideways or lean into the isle WHAT A PATHETICALLY DESIGNED AIRPLANE!!! All staff were great I dealt with

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

Flight bumpy but good. 1 hr 20 mins for luggage not so good.

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

The flight was delayed over 2 hours, we should off left the plane2 late passengers as it’s not fair on everyone who’s followed the rules.

Dreamliner. Yes great if maintained. I didn't see anyones screen work consistently during either of our flights. Worse was their ability to not only dump you out of premium but separate couples and seat someone's carer at the opposite end of the aircraft. This poor gentleman had no hand so his partner who assists him, being seated at the other end of the aircraft, well that really showed us all what Tui think :( It was fairly dire all in all, they advertise all the perks of the dreamliner only in reality you don't have the features and they change the windows and colours to suit their constant sales pitches. Ironically they were so low on stock for the return flight that all their sales pitches were a waste of time! Their contract only favours them and 'operational changes' well they cover every excuse and Tui use it. Surprisingly we haven't reinstalled the Tui app or booked with them since. It's a shame as I rated them highly during the pandemic.

One flight attendant not wearing a mask over nose, 50% of passengers not either, and no effort to correct. Boarding was very late with no information - lots of standing around waiting.
