See link pasted below for GoJet's current DEC and FO bonuses and incentives. Quick answer yes you get your longevity pay and $15k in bonus for current 121 E170 or CL-65 type even as a DEC. I'll be looking at $70/hr and $15k in bonuses. $12k for having E170 type and $3k "training bonus" just for going to GoJet.
