Don't forget the extra fire cover that would be needed. So who picks up the tab would be an interesting question? Would have thought it would be easyjet.
Is the terminal still locked up over night? It used to be 45 minutes after the last arrival but does the airport really turf people out into the night when they have missed the last train home. I would have thought some people would rather wait in the warm for a train the next day.
Most airports seem to have people who are camped out for the night mainly for early morning departures but not Southend?
