That is exactly how our seniority based line bidding works. Seniority 1 in base. Bid 1 line. Seniority last. Bid all lines. SEA is the only base of size. All the others are small so sorting through the lines is simple. We are passed the retirement surge here so movement will stabilize and seniority will stabilize. Reserve and OF(Open Flying) pilots are put on a list after line bidding closes. That list is made up of all the junior pilots in their seat in their base, and all the pilots who opted to cherry pick the regular lines and came up short. The second round of line bidding called Open Flying is built out of everything dumped in line bidding. Reserve line bidding occurs at the same time. All seniority based.
