SAS-A321: fair enough, but the sim is not the only thing holding up training and joining, there's the organizational requirement for joining, i.e. coordination with HR and with Immigration etc. So thats the first limit. Then there's line training to contend with as well. There's no point QR hiring tons of people only for there to be another bottle neck between the TR and Line Training due to a lack of TRI/TREs ahem.
