Sorry, Skipness One Echo me old mucker, but BA's MAN-JFK was not losing money when it was pulled. Far from it, it was profitable at the time. It was pulled because BA believed they could make more money by canning it, moving a few birds around and starting LGW-JFK, It's as simple as that mate.
As for BD, I am very surprised the Caribbean routes are still going to be honest. I've flown there 4 times up front in the last few years and each time around half the cabin was staff.
ORD is a little different, particularly yield wise. Although I was on the 705 a couple of months ago and it was half empty up front, which was handy as some of the new flat seats were goosed. I'm on it again next week and there is still plenty availability.
