I have not flown with Air Transat during covid, but I have used them pre-covid.
Personally, I would pay the extra money and go with Air Canada or West Jet. Our family will NOT be going with Air Transat again. We had used them for a group trip ( wedding ) and had soooooooo much trouble with them.
They charter many of the planes that they use. Out of one departure city, we had an OLD OLD plane, that should only be used for short haul flights (our flight was 6+ hours) in small squishy seats. It had NO technology....meaning it had the overhead bunks with a tv in the bulkhead placed sporatically throughout the plane and your earphones/head phones plugged into the arm rest. They had three movies playing through the trip...2 of which were scratched and didn't play.
We all had trouble logging into their system at the 24 hr mark to pick out seats, and mostly by the time we did, families were split up...even kids NOT sitting with their parents but random strangers. The 1-800 number to contact them was ZERO help, and their website crashed. The
travel agent was " conveniently" away that weekend, and no other agent in that office would help.
They were more than happy to sell us extra excursions at the resort, but when transportation didn't show up, getting our money returned for an excursion we didn't even get to do was like pulling teeth. It took me months to get my money back from them for that one.
We had paid for an upgraded room...and didn't get our upgraded room. And there was also problems with the room for our boys on the first night.
When I"m spending 8000+ on a vacation, I expect to not run into sooo many problems. I understand things happen, but we had many thing happen that left s VERY sour taste in the whole group 50+ people who won't even travel with Air Transat again. Many of them are frequent travellers and won't travel with that company again.
