I've been reflecting in the news of NQY-LHR route. On the face of it, this sounds to be great news.
I would throw some caution to thec wind.
When BA acquired Brymon, one of the first things that happened was to switch the route to the west country over to LGW. JER and IOM routes went the same way. They saw this course of action add commercially attractive.
And so it goes, as soon as these slots become eligible for other operations, you can be sure NQY will be the looser. Will LGW slots be available the service? No.
The transfer to LHR will drive increased connecting traffic, surely when a PSO was agreed it was to ensure that people living in the west country had adequate connectivity to London, to the capital for work etc. Therefore, I suggest that a move to LHR means that the PSO is subsiidising the airline to increase connecting psssengers. No such subsidy is available to other airlines or routes ex NQY for such an activity??
