From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

Air Transat left my luggage back in Montreal and it took them 5 DAYS to get it to Venice. Luckily I was still in town, or else their option was to send my luggage back to my house in CANADA. What a joke! Oh, and I had to find a way to go get it at the airport in Venice, they needed 72 hours more to get it to where I was staying.

I was pleasantly surprised. I booked the "club class" which was basically like Domestic First Class. The service was superior. Food was pretty good. Seats and cabin were comfortable. For the price I paid, I was very pleased.

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.

Boarding was a little chaotic but it was a very large flight. It just wasn’t fast. And there was no noticeable difference between zones boarding.

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 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.

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.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

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."

My flight got canceled. Then AC rebooked me to a next day flight. No compensation no apology. It almost messed up my entire trip and schedule. However, all the unexpepected seems routine and ordinary to AC, so customers need to get used to.

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

Really good. The staff were very helpful throughout the boarding process. The food was surprisingly good. Overall much better experience than previous one.

Because we had to drive to Toronto due to delays in Windsor on our return we had a car in Toronto so we had to drive home

Our flight from Windsor to Toronto had several delays so we had to drive to Toronto in order to catch our flight to London.

Did not appreciate “hidden fees” to check a bag for international flight and purchase a seat to be next to my spouse. Won’t choose this airline again.

I missed my niece’s high school graduation because the flight was delayed 3 hours. I broke down at the airport and on the plane several because of how heartbroken I was to miss it.

It was very dis appointing because of too much delays with our flights.☹️

The flights were pretty close to the scheduled times, all connections were smooth and without additional delays, and my luggage was accounted for throughout the journey. All in all, this was the best travel experience I've had in quite some time.

No meal. Flight crew was wonderful, happily finding me storage for my guitar. THANK YOU!!!

Cancelled flight, that morning! But got us on an Air Canada flight!

Boarding process non existent. No WiFi. No entertainment. Cramped old plane. Worst Kosher meal ever presented on a flight.

Loved the food (vegetarian in our case). Super pleasant. We're in our 60s/70s and not speedy anymore but I never felt rushed. Entertainment choices very current, personalized, and fun. Asked to change seats with a man who had paid for his seats as well but something had occurred in process so he was two rows away from his small daughter. Staff was very efficient at mediating the exchange and gave us a beautiful little travel pack as a gift to agree to it. The seats were comfortable but reclined a bit much for my comfort. I'm glad I'm not claustrophobic as the person in front of me reclined to the max and I felt very enclosed. Very efficient crew simultaneously as super pleasant.

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

boarding needs to be streamlined load the back of the plane first

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Overall great flight experience- on time, lots of food and movies.

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

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.
