While I don't actual figured CDG definitely seems bigger in size but most of that area is quite wasted and not really for use by passengers.
DIA on the other hand makes super use of the space available splitting the sitting and eating areas and the shops.
I wish they had somewhere to sit on the ground floor. I could sit and lust at the cars in peace without making my leg muscles give all hope of rest and aching beyond what I thought was muscularly possible..
Ok boarding time!
