ok the man - jfk
flightcrew are ba mainline
cabin crew- majority are BAR crew on a mainline contract with a few citiexpress crew thrown in for measure
when you book on ba.com it says the route is owned by mainline
the aircraft and route is owned by BA as the aoc for citiexpress only covers europe.
However the money from the route goes into citiexpress coffers, its about the only route that makes money, 2 milion profit at the last shout
