4 weeks ago i would have said Eagle all the way, but now with a possible pending spin off, and Pinnacle having a new contract signed last week (giving at least Mesaba pilots a raise, not 100% sure about everyone, don't want to give out bad info), i would lean towards Pinnacle, they seem like the stronger for the immediate future. Just my .02 cents!
I also agree with Lone Palm, whichever one would give you no commute, or the easiest commute.
