Hotel Tango,
Would you believe the current capacity for the terminal is 18 million, and we are on less than 10 at present !
They really want to develop the old Eurotub built for BA and now incorporated into the one terminal. However it was built for BA hub and spoke and its not possible to convert at reasonable cost BHX claim.
So they will have to demolish it when /if they can afford too. At present the LCC use it most BE/FR.
