In '97 I flew LAX-SFO, CO flew about 4 flights daily between LAX and SFO back then.
Back in the late 80's, maybe as late as '90, perhaps, CO
flew the 747-200 on that route! We'd fly it like SFO
, then the aircraft would change flight numbers and go to EWR
. I think the 747 was 4x daily.
Also other routes I do remember (not counting CALLite, which we try to forget): CO
did experiment with non-hub service to LAS
for a time: SAT
; even CVG
. I remember the CVG
in the early/mid 90's, because it was like a 1030pm flight out of CVG
, and made great oversell protection for our CLE
flight that left like 8pm back then.
