Taking a bicycle back to Canookdia

Back in the day, my hardcore biking mates would travel thru 7 or 10 countries by bike, and whenever they needed to get on a plane, they’d just get a bike box off of a local dealer, take off the front wheel, tape her up, and take it along as luggage.
I mought could want to take a bike along with me in an upcoming trip home to Canadia.
Anyone tried or done this recently or knows why one might not be able to do so?

No problem to take your bike; I take mine with me all the time. Non-asian airlines tend to hassle about it or try to charge a bunch extra, so check with the airline you choose carefully. I usually fly China Airlines or Thai and have never had a problem.

Do you need to box it up?
And do you ever have customs issues?
