Earlier trains from London would be helpful. However I'm curious to know what percentage of Pax are coming by train. I'd suspect its quite low from how full the car parks are and the constant dropping off of people by cars / taxis outside he terminal. A lot of the people using the airport are local to South Essex. In addition there is the new Holiday Inn at the airport opening this month and there is a Premier Inn moff the A127 by the 06 threshold, just 3 mins away by cab.
