Typically, if I'm flying within Canada I fly with WestJet. The people are friendly, they have a good attitiude, if you have to phone them they answer the phone without making you wait for an hour, and the flights are (mostly) on time. I'm a member of their "guest research panel" and often do surveys for them.
However, they don't fly to many international destinations, so for my Botswana trip, I flew with Air Canada. Today I filled out a survey for Air Canada. It was run by Ipsos, and it asked some really good questions. It was also the first time I filled out a survey about a specific flight, rather than a trip. (It was for the Frankfurt - Toronto portion of my trip.)
