Alaska Air forecasting lowered CASM on increased capacity; Southwest up; Republic Airways tumbles

Alaska Air (+1.7%) made one of the few gains among North and South American airlines on Friday (17-Dec-2010) after forecasting a 3-4% year-on-year decline in costs per ASM excluding fuel for FY2010, to between USD8.80 cents and USD8.82 cents. Capacity for the full year is also expected to improve, with the carrier expecting ASMs to be up 4.5% to 27,730 million.
