I travelled through T5 this week and despite the adverse publicity and lack of long haul passengers,the terminal was busy.still a building site,builders pass office in full view,unfinished work everywhere,covered signage,the list just go's on and on.plenty of very upmarket retail space which i am sure would be far better utilised in future for passenger comfort,but little chance of that!if and when BA switch the longhaul operation to T5 the lack of space will become very apparent.one last comment,when boarding my flight,after biometric reconciliation and boarding pass scanned,proceeded down escalator to airbridge,escalator suddenly stopped and automatic doors to airbridge closed,nearly causing passengers to fall forwards.the BA gate agent had to come down escalator,swipe open automatic doors then hold them open manually whilst we proceeded to board.obviously problems with equipment that is currently being used.
