anyone know any good search engines for internal US flights? I'm going to a wedding in Albuqurque in September and want to stop off in Houston for a wkend on the piss with a mate who lives in Houston on the way back. As one way flights are completely extortionate and i cant seem to get flights that'll let me stop over there i think my best bet is to fly in and out of Houston and get an internal flight from there to Albuqurque. [and breathe] so does anyone have any good suggestions for searching internal US flights (whoever's about to say google **** off)? or am i better going direct to the carriers?
