An FYI
On a recent flight out of Carlsbad, CA, there was signage and a note stapled to my ticket jacket that US Airways Express is closing Carlsbad operations as of February 13th, 08.
The frequency was down to once a day (Out 6.15am, in 9:50pm). This will leave United Express as the sole carrier out of CLD.
The note left a Customer Relations number to contact to voice your concern (if you have one

) 480-693-6019/2348
