However, terminal layout is such that exterior doors are not too far from most gates. Smoking permitted freely in the main terminal and baggage areas. No smoking on the Continental concourse. Must go outside to smoke. There is an exit to the parking deck located in the center of the terminal 2 complex, but it is not well marked.
Smoking seems to be permitted freely before security.
Plenty of designated smoking areas after security but not on most concourses. Most gates are not too far from main lobbies and smoking areas. Pretty much a smoke anywhere airport. Only no smoking area noted was in the immigration and customs queues. Smoking allowed in most bars and bars frequently distributed along the concourse.
