I never understood WN's recent plan in FNT. The post FL routes made a fair amount of sense... IIRC: BWI, MCO, TPA, RSW (and I *THINK* LAS, but I could be wrong on that one). But then to up and pull that point to point model and shift virtually everything (short of some seasonal flights) to MDW (which as a metropolis was already overserved by AA & UA flying to ORD).
I really hold out a itty bitty micro shred of hope that WN is leaving because of the proximity to DTW, and will consider services out of MBS (but doubtful considering how they left DAY to focus on CVG).
