Yes, definitely go for DL! I'm working part-time with low hours right now, and am looking for programming jobs with an airline now that I graduated (for those that have been here a while, it will probably be another saga on its own). I'm from MSP originally, and if I could get a job with DL in their corporate offices out there, I'd hold on to it and never let go. DL has a huge variety of destinations (though I think UA will take the #1 spot once the merger goes through, or at least come very close) and some amazing flight benefits - free F if space is there. Definitely a step up from what Spirit will ever be with its Department of Transportation Unintended Consequences fee
