I was making some dummy booking on cx.com and notice there are bonus miles when I book HKG PEK - total miles is 3x original miles in Econ class.

I couldn't find any info on this. Anyone knows what promotion this is?

Asia Miles 2474

Bonus Asia Miles 4948

Total 7422

It's booked in M Class and I'm CX SL

If I logged out and do the booking, the bonus is gone. I'm asking because I have to book through company TA so I'm wondering if I will still get the bonus...
