Sadly, upon using the MH manage my booking, my ticket is now classed as Business Suites - will have to try my luck at the F lounge on the day...

Spoke to Malaysia Airlines - changes won't apply retrospectively, so if you've made an F booking you will still be eligible for F Lounge access on OW partners.

What happens to customers already booked/paid/ticketed in First class? Will we still get Sydney Qantas F Lounge?

I'm booked on a first class flight SYD - NRT via KUL using points, does this mean I won't have access to the Qantas Syd F Lounge? I have already been ticketed in "First" cabin and class "P"... I will check the redemption rates tomorrow and report back here.
