LS are to get 762/3s according to their end of financial year report a couple of months ago. It was also mentioned in Airliner World.
A CO/DL/AA 752 service to EWR/JFK is definately what is needed and a SFB based 763 flying MAN,LBA,NCL and EDI for LS would work very well too.
I wouldn't be surprised if LS received their 762/3s and place them on short haul from MAN and LBA this summer on the bus routes to PMI/AGP/ALC/FAO etc. and then launch long haul during the winter.
