The main reason it's not busy is because the dedicated forum (another website) is where most people go to talk about GLA airport news.
Plenty to look forward to this year with the launch of Air France and Air Canada
also the new FR routes and TCX are basing another aircraft for this coming winter.
Jet2 (as you probably know) have ordered quite a few new aircraft most to replace older planes but some will be used to expand so a 7 base should not be to far away.
