Why Air Canada sucks so much

I just finished 5 days of straight flying last week, and even though United had significant delays and crappy service, Air Canada was worse. I got to the airport several hours early and asked if I could take an earlier flight out, and they said it would require a $42 change fee, which was ridiculous as their plane was half empty. Therefore I decided to just wait for my original flight. Several hours later when my original flight is to be boarded, we are told the plane is broken and the pilots have immigration issues so there will be a 2.5 hour delay while these problems are addressed. I was astonished, not only was I not allowed to take the earlier flight, but my original flight was being delayed without any compensation. In total I spent 5+ hours in the airport waiting for my flight. Ridiculous. That was my return flight too, my original flight out of Toronto was delayed more than an hour as well without any notice until we were already on the plane.

My United flight was pretty bad, when the plane was landing, some kid in a row in front of me threw up on the plane, vommiting over several seats. Unfortunately, the gate people were late coming to the plane AGAIN (every flight they are), so we were stuck inside the pressurized cabin breathing recycled disgusting air.

I really hate flying now, but at least Taiwan, San Francisco and Colorado were all fun.
