Airline stocks have taken a hit following Hurricane Sandy, which caused more than 20,000 North American flights to be cancelled and resulting in an estimated $190 million in lost revenue. Legacy carriers Delta Air Lines (NYSE:DAL) and United Continental (NASDAQ:UAL) are expected to take the brunt of the damage -- an estimated $95 million combined, according to analyst firm Hunter Keay -- but Southwest Airlines (NYSE:LUV) could also lose $10 million.

The timing stinks. October traffic fell 2.4% year over year while available seat miles declined 1.6%. Load factor fell 70 basis points to 80.7%. Fewer planes flying fewer routes at a lower capacity doesn't bode well for fourth-quarter results. Yet, given Southwest's valuation, dividend (a rarity among airlines), and popularity among fliers, there's still reason to believe in this business.
