Why does date of hire suck? The argument has always been "NJI shouldn't be separate, we all work for the same company." Well then, we all got hired by the same company 13, 10, 8, or however many years ago. You can't have it both ways.
By the way RTRHD, your new merged seniority number will mean everything when the IV fleet begins to slowly disappear and the pilots in that fleet are required to bid new equipment. Unless there is a side LOA in the integration agreement that keeps them in the G fleet, they will have to bid whatever their new seniority will hold. The LOA to the IBB only guarantees CURRENT seat and pay.
Long time down the road, I know, but it's still there.
