I remember when Capital Airlines ceased trading, Loganair picked up the GLA-LBA service within a couple of days. They didn't hang around then either, though I concede there was no LBA base set up by Logan.
Interestingly, that route has been operated by British Midland for two periods, Loganair for two periods, Dan Air, Metropolitan, Brown Air, Capital and Manx. The route is not currently served. I hope Logan is aware of this.
