Rivet - the Amsterdam route had 78 people each way (rounded it to 80) so 156 people flying to / from MSE. Unlike most other routes, KLM operate just 2 round trips each day - 2 arrivals and 2 departures, instead of 3 round trips.
There is a definite need for a bus between Manston airport and a local train station as Ramsgate station is a fair walk from Ramsgate town centre.
