I'm booked in F on CX472 (shorthaul HKG-TPE) through Avios points. Checking flightaware it's been served by three different types of aircraft in the past ten days: 777, 333, and once by a 350. From my understanding only the 777 has F, and only some configs of it. I have no idea how to determine config except by specifically looking at seat map for each flight (which seems tedious).

I'm aware equipment changes on shorthauls are common.

1) If an equipment change occurs, as someone statusless and in a low value fare, is there a chance I'll actually end up in economy (e.g. because fewer J seats on new plane)?

2) Do I have any recourse from Avios or CX if downgraded from F to J or Y? If it happened T-24, would CX offer to change flights to one with F considering there are so many daily flights?

3) When do equipment swaps usually occur?

4) What's the best way to stay informed? By creating an EF flight alert or must I constantly re-search the flight's seat map?

Sorry for the questions; it feels like there's a lot of material to absorb. New to CX, flying 40k miles with them this year
