Several posts in the past have made reference to MSE being an airport capable of serving London and have based their hopes for scheduled pax services on this assumption.
Elsewhere on this forum SEN is reported to have yesterday received 67 additional re-routed or diverted inbound flights including BA, while it sounds as if MSE received a mere handful.
Surely that very fact puts MSE's potential as a 'London' airport into its proper prespective. London Southend - yes. London Manston - unrealistic.
