Thanks for the info. I think I will take my chance and will be wearing my running shoes. It does not concern me about the checked baggage as long as the airlines will not loose it and send it to me in a timely manner ^

Question though:
in case if I misconnect the Singapore flight for a rewards seat like this, will sq book me a seat on their next SQ flight to SIN upon the actual 'seat availability' or based on their 'award seat availability' as of my status with *A?
