In this way, the route should then be achieving 80%+ load factor which should arguably benefit the region a little more
"benefit the region" is certainly an arguable proposition. Who would take the £50 seats? More Dundee business people? And how would them flying from DND instead of EDI (or train) benefit the region?
And if it was outbound holidaymakers on the £50 seats, how does that benefit the region?
Would £50 seats result in more inward tourists or business people that wouldn't otherwise have come to Tayside at all? I suspect the jury's gonna be out on that for a long time
