This is kind of ironic, considering there were some vocal 9E guys saying they'd deny GoJet pilots a jumpseat.
Don't start jumpseat wars. I remember doing a flight to MEM one time and we had 2 AA jumpseaters. This was after when the 9E union wanted pilots to limit AA jumpseaters to just 1, regardless of seats open, to reciprocate what AA gives us. AA's policy is management-set, and some airlines are on the unlimited list, others are not. The gate agent will see it, and then act accordingly. It isn't the pilot's fault! At least my CA was cool, and said he'd take both AA pilots. The AA guys were super happy to get home. Of course, this CA could have been a "union-by-the-book" and denied one AA pilot a ride home. But he was cool and didn't believe in that jumpseat war crap. A pilot is trying to get home, then get him home. We've all commuted at some point.
