Well, highly possible. But you'd piss off a whole bunch of prop FO's who are waiting for a chance to upgrade on a widebody worldwide operation with less than 3000 total Jet time
Wouldn't be an EK thread without some bashing directed at the turboprop drivers
If the pilots' seniority allows for upgrade, they meet the requirements for upgrade, have the correct attitude for upgrade and pass the upgrade, then they should be allowed to upgrade. It's all part of the same Check and Training system that ALL pilots are trained and examined by.
