But Lyddair operate a plane with 16 seats even if it is a daily service. Has anyone tried a daily service with a 16 seater plane out of Manston to know whether there is a comparision?
After all an airline operates scheduled flights out of Brighton City airport, more frequently known as Shoreham. I don't think that that means that Shoreham will become the next large airport.
Tiny planes operating short routes may work from any airport as they don;t need so much infrastructure to support them, they don;t need so many passengers to break even etc.
There is a lot of difference between a tiny plane operating one route and lots of planes operating lots of routes.
