Bring all the regional pilots onto the the mainline seniority lists and working under the mainline contracts. Do that AND move anyone age 65+ to the bottom of the seniority list while keeping their longevity for pay and other benefits. Heck they can even keep their last category pay for all I care. Then and only then would I even think of entertaining an age increase. Let’s see how many stick around flying right seat in an RJ 5-6 legs a day for $350/hr.
Age 65 combined with 2008 ruined me financially and it took a lot longer than five years to recover from. Probably wouldn’t have been furloughed or lost my home if the age had stayed at 60.
