My buddy at Frontier says their flights are pretty darn full.

I think the ULCC/LCC model is more immune to this. It is hard to make money when you fly 777/787's to Asia and Europe, and those PAX board via DFW and ORD, fed by 737/A320s.

the Big-3 model depends on the business traveler for revenue. Corporate America, Federal Government, and others are cancelling meetings and conferences, and embracing web conferencing/etc.

ULCC/LCC are possibly better able to endure this storm.

My opinion
