I'm sure most people coming here now are using Spirit as a stepping stone/free A320 type rating. I went from Great Lakes to Ryan International in 1999 just to get a type and to get out of Great Lakes, I thought I'd be at a major in a year or two. Well, 9/11 put a stop to that, but I'm glad I wasn't at stuck at Great Lakes...

If the majors never call, Spirit is probably better than some regionals and most 135 operations.
