4 reasons;
1) The Gatwick style of flying is very cost effective
2) The segregated Longhaul/shorthaul style of flying is expensive for the airline and has been abandoned by many of our competitors. It just isn't an efficient way to use our resources
3) Sat in a meeting with a Crew Manager that strongly hinted this was on the way.
4) BASSA communication a few weeks ago signalling/hinting things would soon change at LHR
How it will be implemented I don't know ... I would imagine the company would start with all future new-hires and/or shorthaul crew.
My own conclusion is that this WW / EF thing is on its way out. How quickly it will be implemented I don't know.
