I have a 38 inch tall foldable chair - http://www.amazon.com/gp/product/B00339C3RI
which doesn't fit in my luggage.
I am traveling by Singapore Airlines, and while their Baggage allowance section (http://www.singaporeair.com/jsp/cms/en_UK/travel_information/baggage-allowance.jsp) talks about wheelchairs & sports equipment. I can't seem to find much on transporting a regular oversized piece of luggage.
What would be the cheapest/best option to transport it in airline baggage? Is there any other option?
