Do they have smoking areas?

If you're unable to find a place to sneak a drag in the airport, you can usually catch a smoke in the airplane lavatory, you'll just need to disable the smoke detector first.

There are designated areas

Not once inside I don't think

I'm not.a smoker...but I guess same rule applies to all Intl.Airports. Only outside in the designated areas

I've seen people smoking outside baggage claim. No smoking areas within the airport. Technically not supposed to smoke within 100 feet of airport.
