All furloughees at dal/nwa from the early 2000's (after 9/11) were given longevity for pay purposes, but that longevity didn't translate onto the "seniority list", - as was said, there were 2007 dal hires that went ahead of 2000 nwa hires on the SL. Toward the top of the list, there were also dal 1986 hires who went ahead of 1979 nwa hires...those were the extremes, though, for the majority in the middle of the list, the avg loss of DOH seniority for the nwa guys was about 2-3 years. (there was a group of about 150 dal 1991 hires who went behind nwa 1995 hires, -the only place on the list where it was reversed) This might be a key point though....even though there was a significant difference in DOH seniority....-almost everyone remained within 1-2% of their original seniority at their respective airline.

Everyone kept their original DOH for longevity/pay purposes, and for non-rev priority purposes.
