I am DTW based but live in Philly for Endeavor. FWIW the commute isn't that bad going my way. I get up at 6:30am to commute to my first day of reserve in Detroit, and am always back at my door by 1030pm my last day. I shouldn't be on reserve much longer, and I will be NYC based pretty soon. Good luck with your choice. Endeavor seems as good a place to be as any right now. Everyone seems optimistic. I was on military leave for the dark days the last few years. Honestly though, don't commute if you can help it. By far the biggest factor in choosing a regional, like everyone else here says. If you lived in Philly I would say go Piedmont hands down, even though I want you below me on the seniority list at Endeavor :-D
PM me if you have any questions about Endeavor.
