Not sure how helpful this well be as see your inquiry was three weeks ago.
I have had a bit of experience shipping my mountain bike to a flew places from Canada, and although I see on the post there may be more restrictions then when I last did it. But the way I have shipped my bike is using a product that holds the bike and allows you to fly with it as check-in luggage.
I am not at home right now or could check the bag, I am actually in Europe right now on a five week motobike trip, but will check when I get back to Canada and let you know the product name for future reference.
Velo-bag seems to ring a bell?
Anyhow, as per the other post, the disasembly required is very minimul:
Handlebars off, turned sideways and taped,
Pedals off ( I wrap them in bubble wrap and zap strap them to the frame.
Seat and seat post off ( I tape it to the seat tube inverted)
Front tire off (It goes in its own little pouch in the bag)
That about it. Places I have taken it as checked in luggage are Eire, Trinidad and Tobago, Fiji, Philipennes, Cuba, Mexico to name a few.
Had a quick peek on the internet. Here is a page showing some products, but I do not see the one we used, but they are very similar.
Mountain Bike Bags
Ours was a soft shell bag with extra padding at the hubs for protection.
One thing we found that often charter airlines we a little more accomadating with bikes as they also take skiis, surfboards etc.
With the larger airlines, we always tried to check in advance to be sure.
Hope that helps a bit!
