That wording sounds entirely too weird.... There is more to it. We all know it never truely is black and white. ASA management seems entirely TOO smart to allow their pilots to continue to gain LONGEVITY while on furlough. I do not believe there is ONE single airline out there that does that, so ASA would be a first. As a former furlough, I had to come back and work three months before I recieved my 2nd year pay. I was on property for 9 months, thus my LONGEVITY stopped at 9 months... Then when called back I had an, "Adjusted New hire date" in which all my furture payraises were based off of. It so happen to be exactly 90 days from the date of my recall....
Seniority is a given I believe at most. As long as your contract does not say you only have recall rights for a set amount of time. Then I believe if that time expires the company can do whatever they wish... Again I do not believe there are many of these out there any more.... I would contact your furlough rep or local union status rep and get an answer... The INTENT of a contract is something a lot of line pilots simply do not know... Only the few whom negotiated the contract seem to TRUELY know what the intent behind a lot of the BS is...
