If there was a few bob to made in flying cargo between NCL and P.City, I suspect BMI would arrange Atlas to do the work for them-because I somehow doubt many Geordies would want to fly to Panama (except perhaps MI6!!)
I seriously see HKG and perhaps DEL & DXB as strong contenders-if BMI manages to get slots & capacity on hand. HKG via DXB could be a possibility, but I doubt it would be popular (but bear in mind the CX flight from MAN is not non-stop).
I would love to see BMI Airbus 340's flying into Asia and perhaps......South America (Brazil & Argentina??!!). Then again, is there a suitable demand for those flights out of MAN or even EDI??
As some people have said, BMI will probably want to focus on North America in the short-term.
