In terms of easyjet running MAN-MAD, could they run 2 daily LPL and 2 daily MAN.
What about:
07:00 LPL dep (LPL based a/c), and 15:00 (LPL based a/c)
09:00 MAN dep (MAD based a/c) and 17:00 (MAN based a/c)
therfore, giving both cities a chance at the route, 4 seperate departure times so not to overlap too much.
Ive give MAN the later deps as the morning flight could utilise a MAD based fram, as seen as frames are an issue at MAN, and also LPL gets the bulk morning traffic whilst MAN gets the bulk evening traffic.
