Possibly the worst airline I've flown. Flight attendants are hostile, unfriendly and unhelpful. AND your flight is likely to be delayed by hours, meaning that you will miss your connection. Every flight I've flown on AC has been delayed, with 45 minutes being the BRIEFEST delay I've experienced. My current flight is already delayed over one hour and we are headed back to the gate instead of taking off. I'd love to come back to Montreal, but I won't if I have to fly Air Canada. It's that bad! Canada: love the politics, love the healthcare system, love the food, but what the heck happened to the national airline???
