Doesn't the US Airways shuttle operate on leased slots from NW
? Maybe it doesn't but I remember reading that somewhere. Prior to 1991, EA
had the most slots at DCA
and IRC NW
bought the vast majority of Eastern held National slots from the bankrupcy court in mid 1991. NW
operated a minihib from DCA
for a while but by early 1993 shut it down and began leasing slots.
