Reserve life right now is bad. Count on being assigned a short call, field standby or a trip all 18 days. Long call is a fiction, does not exist. Global reserve rules leave you at he company’s whim 24-25 days a month….commuting to that is horrendous., third world.
So it’ll be better as a line holder you say. 85-90 hour lines are normal. Trip trading is also a fiction, No way to improve your schedule. Only way to improve is to be in the top 25% or so of your BES. Frequent reassignments, many of which are into days off, which the company is loathe to restore.
Everyone is overworked and jerked around. Go anywhere else if you can.
