I have an early morning flight (7 am) out of CDG on Iberia Express, connecting in MAD for an IB flight to the US. (Prior to this, I didn't even realize that CDG had a third terminal.) What can I expect in regards to finding food/coffee and just a place to hang out while I wait for my flight? On the IB forum, a helpful poster classified T3 as a "large shed," so my expectations are rather low. But still hoping to come up with a basic plan for the early morning.
