We had a First Officer at Envoy with NO turbine PIC time who got hired at United about a year ago, then within less than a year he left United to go to AA. That perfectly shows that Upgrades and Turbine PIC time is no longer a necessity to get on with majors. Get your connections and recs and you'll be fine. If your plan is to go to AA I would say you have a better chance getting on with them being at Envoy with flow through and a closer work relationship/environment with AA.
