The airline stocks will continue to climb as long as there is no dip in economy.
As far as the weather is concerned, the impact to the airlines is minimal when you consider higher load factors during and after these wx events.
The decrease in fuel costs during this period will offset some of their loses.
A) They will certainly take a revenue hit. They will break it out though, so analysts can see what the WX cost.
B) The earnings hit will not be that bad. The per ASM numbers actually get better (higher loads, plus emergency bookings).
C) Q1 is traditionally a losing Q for airlines. They were looking for a profit this time, and I suspect they will still see such (but I have made no attempt to guess the numbers).
D) Do you really think you are the only person who knows this tidbit of info? It is well priced in as of now.
