For US Airways come late November, with flights to just Charlotte, Philadelphia, Washington Reagan National, and Phoenix. That will leave the airline with about 21 flights a day at Las Vegas, down from 35 currently and around 140 a day in the summer of 2006.

The reductions at LAS is part of the carrier’s strategy of focusing its operations on places were it is strongest, which would be, well, Charlotte, Philadelphia, Washington Reagan National, and Phoenix. Expect this transformation to be complete in about a year, subject to the feds approving the LaGuardia/Reagan National slot swap with Delta.
