Surely it's not the size of the plane that matters - it's whether a service makes money. That is what makes a route sustainable!
True,for the airlines.
But for the airport, surely passenger throughput means more?
The more passengers, the more made on retail, etc which is where the money is for the airport.
Also, the bigger the aircraft, the higher the landing/parking/handling fee's
Bring back Air Wales. A similar size operation, routes such as LPL/MAN/NCL/ABZ/DUB/ORK/INV/LCY/BRU could work with the right plan!!
