With regards to your last comment 'men in suits won't like sitting on the floor and quite like airbridges'
The original CGI images and videos released of the redevelopment showed many men in suits with briefcases and rolling bags but in your various pictures you have posted I've not seen one man in a suit and believe me I have enlarged them to see if I can make any out but none
So obviously the man in suit who quite likes airbridges is not even seen at LTN and are using more superior airports for there travels, I don't blame them with the images that you have posted.
I had my own feeling that this whole redevelopment at LTN wouldn't achieve much and has only deteriorated the image of the airport even more so to the traveling public and media.
