Last week, we saw fourth quarter earnings from American, Continental, and Southwest, and the rest of the big carriers will have their turn this week. Here’s a schedule – each airline’s name links to its investor relations page for reference.
Tuesday, January 26
Allegiant
Delta
Wednesday, January 27
AirTran
United
Thursday, January 28
Alaska
JetBlue
US Airways

Alaska will be Thursday as well. Should be good news.
Just updated – thanks Ryan!
