Changi Airport’s mix of outdoor gardens and indoor smoking areas makes it one of the best transit hubs in Asia for smokers. If connecting onward to Bangkok Suvarnabhumi Airport, you will find enclosed smoking rooms in the airside concourse there as well. Travelers heading to Kuala Lumpur International Airport or Tokyo Haneda Airport can also expect indoor smoking rooms after security at both destinations.
