I'm told it does, Envoy - AA your vacaction time accured to that point, grade continues. For example 6 yr Envoy flow to AA will start AA with 6yr level vacation.

IF I'VE BEEN GIVEN THE WRONG INFO BY AN AA PILOT please advise.

I know 1 Exception to all this is if you decided to get hired off the street to AA and not wait for the flow.

Same for 401K... it continues to AA level and rate/grade/year in service, seamless Xfer like a "career."
