I googled Porter Airlines and the first headline link was "Porter Airlines Flights from Toronto". Apparently it took me to a 3rd party company - "My flight search.com" which i didn't realize. I booked a flight with return for $260 + and received a confirmed email. Half an hour later, this person calls from "My flight search" and said the flight price had gone up $100 and we were unable to keep our initial confirmed price even after it being CONFIRMED. Not to mention, the price was in US Dollars which did not state. I cancelled the flight. Went online, and still it was the same $250 + i originally booked. I called back, and they said the computers take time to process new prices. We called porter airlines and they were aware of a third party company, and did not have any price point similar to the one i booked.
SOUNDS LIKE A SCAM TO ME.
