SkyWest Airlines signed a letter of intent to operate14 Bombardier CRJ200s on Phoenix-linked US Airways Express services from 2012, adding US Airways to its roster of capacity purchase agreements with mainline US carriers. The three-year agreement, subject to relevant approvals, also provides options to upgrade to larger CRJ700 aircraft.

SkyWest will replace CRJ200 and Dash 8 Express service currently provided to  US Airways in the Phoenix hub by Mesa Airlines. The Utah-based regional said it anticipated that the aircraft used on the US services will be "allocated from SkyWest's existing fleet." It added that it will be "compensated in similar fashion to … existing capacity purchase agreements with other major codeshare partners."
