And now for something completely different... actual information.
It will take you 3 hours to drive from Edmonton to Calgary. Make sure you incorporate that into your plan. Come on a Wednesday. That is the day for hangar tours and to meet the people who do the hiring. You would like to talk to Mr. Proban. If he is out, then usually one of the other HR people would be happy to speak with you. If you know anyone who works at WestJet, get them to take you in and introduce you around.
Good luck.
