This is very disappointing; I'd been waiting anxiously for this - on tenterhooks!
Can't they just negotiate with the planning people? Surely intense (ouch!) negotiations should do the trick
Seriously, though, did nobody in the DAA's planning department (quickly becoming an oxymoron) pipe up and say "we might need planning for this!"; this proposal is hardly new. We can express resigned acceptance of the fact that they can't plan a new terminal … but not being able to plan a tent, I mean - come on!!!!
Still, not the end of the world; they can always hand out umbrellas.
(Just a thought; if they put the waiting area in a covered part of the parking lot - say level 4 or 5, they wouldn't need a marquee? It's the same thing, surely, … to all intents and purposes? )
