When I was going to college in BNA, I was a WN flier (the frequency and cheapness of MDW flights was great). Now that my parents no longer live in Chicago, but abroad (Canada) and my travel is much more varied, I am a NW (and now, sadly, DL) flier. While I'm not happy about the devaluations to the program which have occured since DL's takeover, I'm sticking with them because they still represent the best options for me.
