Not necessarily a Transat issue but it took 2 hours to go through immigration. Tried to reach out to Transat for resolution but was unable to reach an agent.

Not necessarily a Transat issue but it took 2 hours to go through immigration. Tried to reach out to Transat for resolution but was unable to reach an agent.

The flight was excellent, once it started, however we were delayed two hours when the first plane’s engines wouldn’t start. They found another identical plane and transferred us and our luggage in under two hours and made up almost an hour in the air.

Really low cost trip for the huge amount I paid…o paid 550 dollars just for the trip, one way trip, plus 95 for 1 luggage’s and the second 135 dollars…no blanket, not headphones for entertainment, food was served after 3 hours and 2 hours after, breakfast was served Bad, low cost company for high prices

The flight and crew were good. Departure and arrival were timely. Check-in was professional and helpful in Malaga on return trip (same on outbound trip from Toronto). The ad before ach program was punishing - specifically for the internet/data service with the content creator that was showed twice in each ad pod. It was so annoying I made an effort to forget the name and would not use the service. Provide an opportunity to fast forward or skip the darn ads once they have been initially viewed.

Extra attention to kids, thank you, we appreciate! Perfect landing

Over the wing seat at emergency exit only downside people using lavatory have no respect and wait in the space

Flight delayed any hour and couple of big gate changes

The pilot came out and chatted with the passengers. He explained why there was a slight delay. The crew was excellent. Very helpful. I had to buy meals for my whole family and they were in different seats, so the crew had to deal with that. They were very pleasant and accommodating and did a great job!

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

Food was excellent. Service was very good. Staff was very helpful to all passengers.

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

I did not fly by vergin atlantic from bangalore to vasco da gama

Your flight delayed at Heathrow n I almost missed my mother funeral.you idiots. I had to waste 10 hours in different airports. Thank your stars I'm not suing you.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

We had an unfortunate experience where we had to leave the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason given was that a passenger felt ill and had to cancel their plans and therefor their luggage had to be found and removed.

Abandoned me in hallway in a wheelchair… which I asked for because I sprained my back. After waiting in the hallway, I decided to walk the rest of the way since someone respecting me up.. My experience with the united was totally the opposite. Wheelchair access, propped swift and save me a lot of grief. Air Canada totally disorganized.

No issues other than paying twice for my seat selection.

Bad experience boarding and flight got delayed didn’t make it to my next flight

Everything was great, clean plane and washrooms. Flight was on time, excellent boarding process

The app was great, service was wonderful, everything was quick and easy

The food on the trip Toronto to Athens could be better: the chicken didn’t taste good.

Horrible. Multiple delays for every reason imaginable. Missed connection which led to missing work. How does a plane make a detour to refuel. Do the fueling then have to refuel a second time at the exact same spot? Mind blowing.

Conflicting information provided about baggage allowance. One screen said I had a carry on and another said I didnt.

The 787 Dreamliner that we flew on was relatively new and a nice aircraft. We flew on a 777 which was noticeably older and the seats were average” but the 787 was very nice, especially for the price. No window blinds anymore, instead high tech adjustable polychromatic glass!! Nice.

I had a great experience at YUL Air Canada. The service was top drawer as I needed help to board.

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.

The flight was delayed by an hour. Made the connection uncomfortably tight.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

The flight was ok, the flight attendants were lovely, the movies were good, the food was ok, and I am just sad because my luggage didn't arrive with me in Iasi because the flight from Vancouver to Frankfurt was delayed and then I barely made the rest of my flights. Also, there was no real support once I got off each of the flights. There was nobody to ask about gate or where to be and for example when I got off in Vienna to catch the flight to Iasi there was no screen where I could read the gate and time of departure of the plane. I was going crazy trying to find the plane to Iasi and I barely made it. When my luggage finally arrived home it was broken. The handle was completely broken and that was not so good. I am in a visit here, in Romania, and I will have to buy a new luggage.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

The food was very good and it came multiple times

Flight from LGW to JFK delayed by 4 hrs No explanation given until the pilot said the delay due to planned maintenance on the aircraft

We arrived late to London, and consequently were 5 min. late to be allowed through security for our next flight. Even though dozens of people missed the same flight, BA did not radio ahead to hold open security for an extra 5-10 min. to allow people to get on the flight. This caused an additional 6 hour delay in London after waiting over an hour in Customer Service to get rebooked. They did not have enough staff on hand to help people in a timely manner. Not at all happy with the BA's customer care or customer service.

All service prior to the flight was terrible: online check-in not working, no customer service tel,, multiple airport scanners not working, A huge mess.

CONSTANT ERROR MESSAGE THAT THE WIFI COULD NOT BE PURCHASED DUE TO INABILITY TO CONNECT PAYMENT SYSTEM VIA SATELLITE. THIS HAPPENED IN BOTH DIRECTIONS. THE MAIN REASON I TRAVEL IN PRIORITY IS TO BE ABLE TO WORK FOR WHICH I NEED ACCESS TO INTERNET. .

They lost my luggage. Lady who was helping with it in Austin was rude. Not very helpful!

Waited 3.25 hours in plane only to have the flight cancelled.

The business class seat was an uncomfortable conversion of a main cabin seat well below the quality of even the budget carriers in the US. I would have never paid for business class if would have known I get the same seat as main cabin. BA has gone down hill significantly in this class of service.

More space, of course. a footrest! more room to walk. Movie selection was awful. Some good documentaries would help if the movies can't be better. The flight itself was great, crew was great.

I had a great experience on this flight! The crew was extremely helpful and attentive. Seats are very comfortable and the in flight entertainment was excellent.
