Is it possible to earn points on multiple frequent flyer programs when booking a flight?

Hi there,
If I’m a member of multiple programmes, can I use more than one member numbers when I book a flight to earn points ie: if I’m a qantas frequent flyer and I’m also an Asia mile and want to use both member numbers on my flights

Never ever. Ask yourself if airlines would ever permit this?

No. If you do, it was an error, so keep quiet about it!
