Longhaul through Heathrow.
I would rather fly from MAN any time but now that malaysian have left the fold i find i can get business fares to the far east and oz cheaper from LON than MAN.I travel to the airport by hire car so the cost of getting to the airport is about the same although even the land journey to MAN is much less hassle than LHR or LGW.However as i pick up my own costs the price decides and lower cost deals with the decent airlines don't seem to include MAN.. .
