Millenium/Singapore wheelchairs available?

Hoping someone has some insight on this.

I slipped on ice this morning, and am now required to wear a knee brace(6wks) limiting my movement. We fly tomorrow and are due to board the Millennium in Singapore on the 9th.

Can anyone tell me if wheel chairs are available on board. The crutches I have are quite exhausting for longer distances. If one is available do I need to call ahead and reserve?

Wheelchairs should be available to help you through the terminal and onto the ship, but once onboard, if you need a wheelchair you need to bring your own. EM
