Uh yeah, to back your claim up, my own cameo lists indicated
that 9512G went stuck on Sv 291 from 27 Nov as well. 9243H I
spotted the next few days on Sv 23. So I think it's probably
true.
I think 291 is kicking out the Batch 1s (they kicked out 9240X
alr). Sv 23's 9260H & possily 9243H are likely short-term
measures, think Sv 23 is getting Wrights soon by the looks of
it.
Currently 291's fleet got unstable again, with 9567Z on 9243h
slot ytd and 9512G on 8547's slot ytd...
