Southwest's cost of carrying each passenger one mile, a closely watched measurement in the industry, jumped 6.4 percent not counting fuel. That's a much bigger increase than overall inflation, but Southwest said it held costs down by reducing advertising and getting a rebate on excess security fees it has paid to the Transportation Security Administration since 2005.
The airline said it expects a similar increase in costs in the third quarter.
Unless you guys keep raising fares....costs will have to come down some other way....
