One longevity list. Bottom of the list for bidding schedules and vacation, but longevity for pay. Get paid for the experience you bring. Since people like to compare pilots to doctors, the AMA spells out the strict requirements of newhire Doctors that companies must hire. Make it the same. Companies can only go so long by hiring bottom barrel for experience before they are forced to hire guys throughout the experience spectrum. This pill would have been easiest to swallow for the legacies in 2010-2013 when virtually every pilot was topped at the 12 yr scale anyway.
But alas it'll never happen.
