In the past there certainly have been pilots that have been accepted into CX with around 1500hrs. I guess the key thing to remember is that the '1000hrs' that they state as their minimums are exactly that, only minimums. On average most guys have in excess of 3000hrs and Turboprop time.
With so many unemployed experienced drivers out there at the moment looking for jobs, I'd have to say CX will have some pretty experienced guys on file waiting for interviews etc when/if recruitment picks up again.
