AF cutting flights to HKG
 

It appears that AF is cutting quite a few flights to/from HKG in the coming days.CX too.
Then it seem to be coordinating with CX, so that the two airlines are alternating daily flights from 10 March or so.

KL is also adjusting capacity

This is a bit misleading. For example in the week 8-14 March, AF188 only operate three/seven on 8, 11 and 13. My guess is that on three other days of the week, they put pax and CX260 (A350), and no flights on Tuesday. That's a total of six weekly, but only three on AF metal.
And the timing of CX is 12:15 (noon) while AF188 was 23:30 (midnight).

I think AF rebooks 1st on KL (and vice-versa) before even considering CX.

That may very well be. But if AF and CX coordinated schedule, as my source in HK told me,AF and CX could have a specific arrangement..
But note that there are days when neither AF or KL operate (like ( March in the week I selected).
And little evidence of cancellation coordination between KL and CX. But I strongly doubt that two flights KL and CX on the same day make any sense given the loads.The seat maps are just plain empty in all cabins.

There are both Special Prorate Agreements and interlining between AF and CX indeed.

Friends on cancelled AF or CX flights get automatically offered the nonstop flight of the day, as AF and CX alternate.
It probably won't be long before a similar arrangement with KE on ICN. All companies are cancelling business trips to Korea.
