(1) If you arrive at las airport by CAT bus (#108 or #109), you enter the airport at level 0; the escalator (or elevator) terminates a few feet from the generic terminals (on the 2nd floor.)
(2) The previous two times I departed on a Sunday night from las, the "dedicated" aa terminals were not working.
Thanks about the "status" note; in another thread other fter's mentioned this, but it appeared to me that they were lucky that the tsa agent sent them to fc line.
