I can’t help but think that this airline is about 20-30 years too late and therefore outdated already.
The Canary Islands are already well served in volume of seats by the likes of EasyJet, Ryanair, Wizz, Jet2 and even Tui (pre covid of course).
It’s best hopes are as mentioned in the above post, routes to such smaller U.K. regionals like HUY, NWI, NQY, INV. Other than that I don’t really see its purpose or longevity.
