Transat Airlines is the worst airlines company I have ever seen and needs to be reported to department of transportation. My father had a flight scheduled to travel to YUL. I purchased the ticket for 1800+ k and on my dad's way to the hospital, he had a severe pulmonary emphysema illness where he was taken straight to the ER. I called and canceled the filght and informed them of the situation. They asked me to provide the documentation of the ER in order to get a credit, which I did. They refused to either give me a voucher or credit for my dad to travel. They require that I purchase a new ticket in order for my dad to travel. They are very rude, unprofessional, heartless, cruel people that I have ever seen. Do not travel with this company. They also have fake customer service number on their website when you call them to spend 3 hours on hold and can't never speak to an agent. Run away from them, they are bad!!!!!

Had an absolutely horrible experience with a trip booked through the Air Transat website, with a connecting flight operated by Porter. Total fail by both companies! When showing up for initial flight operated by Air Transat, was refused boarding and handed a phone number to try to fix it. After about a half hour on hold and speaking to heavily accented employee, found that they’d changed my booking to several days later. No emails, no notice whatsoever, no offers of compensation, nothing. If that wasn’t bad enough, when I eventually took the flight they rebooked me on, upon arrival at ticketing for the second leg of my trip (this time operated by Porter), I was again refused boarding. This time they said I owed them a large sum of money (twice the price of flights booked) and would not be allowed to board until it was paid. Upon contacting both Air Transat and Porter (both at ticketing and through their phone line), both claimed it was the other’s fault. Spend hours dealing with them, missed the flight, and eventually had no choice but to give in to their extortion.

If I could leave negative stars I would. It was the worst experience I have ever had. They are not willing to work with you at all and take your money any chance they get. Not only were the employees checking us in useless but so were the phone lines. We had to prior notice of vaccination requirement and had to miss our flight. We were told that if we called the customer service number they would help us rebook with a small fee. After being on hold for 10 hours I was finally able to talks to someone and they let us know that they would not do anything and we would have to book a whole new flight. Terrible experience, never flying with them again. KLM is way more helpful and care about their customers. Would not recommend!
