There would be exclusive 'Under Class' lounges for the pax, ideally outside so they can have a last few smokes before boarding. To make them feel at home, plasma TVs would provide 24 hour rolling 'Trisha' or local equivalent. Supplies of dirty clothing would have to be ordered in to be left strewn around the floors and cheap sofas provided (custom made with cigarette burns and rips).
I'm not sure if any perfume manufacturers have managed to bottle up the unique aroma of the Chav home (stale sweat, filth and animal matter) but if not, then Brut would probably have to be sprayed liberally.
The carpets would also need specially treating till they are sticky enough for your feet to adhere (pax would be requested to wipe their feet on the way out).
Glazing would not be a problem as the lounge would just need a few sheets of plywood where the windows used to be.
