Of course I wouldn't expect anything regular or business orientated, but if BA can serve LBA, IBZ, PMI as well as the charters out of LHR then I see no reason why NQY doesn't stand a chance. Nobody ever said LCY would get its IOM route. It did, and on a Saab 2000... whoever says they saw that coming is telling a porky.
LCY-IOM was an existing route run for years when EuroManx built up the route well, Aer Arann continued it and only left for SEN for strategic reasons. BA / CFE just picked up someone else's market when they walked off. Whereas LBA is the overflow from MAN where BA know the existing Exec Club members in the region who use MAN as well as nicking existing traffic currently connecting with KLM.
LBA has a little under three million passengers and is borderline LHR material, currently struggling but with some hope to make it.
NQY has under 170,000! In all seriousness you'd see JER, GCI and INV well before NQY ever got a LHR link.
Apples and pears.
