Are you at AA? You can project your future seniority into different bid statuses and see what that schedule and pay is. Use the tools to find your seniority progression and compare today's 3XP's at your future seniority. In general the flying should be fairly stable going forward. A change of G3 vs G4 seniority should occur as 767's retire and are replaced by 787's. The junior 787 flying will be more senior than the current 767 seniority numbers due to the 20% pay raise(G3 vs G4).
Third year pay is roughly $165K. Fifth year should be in the $185K+ range and possibly up to $220K (?) junior G4 bases?
If you can hold CA in five years you'll be at $225K with a lower probability of $250K. Probably 2(?) yrs to be a lineholder ((2025). As a lineholder $300K+ is very achievable.
You say a RIF is coming. Will the corporate flight department survive the downturn? What percentage do you expect to get furloughed? When? That estimate can be used to compare future relative seniority vs today. If it's 1000 furloughs depending upon your current seniority, and which year you project the furlough to occur, you might have enough seniority to stay on the 'not on reserve' side of the curve.
With 800-900 retirements per year starting in approx. 3 years a small furlough (5%) probably wouldn't be worth it due to the training bubble that it would generate. Fifteen percent furloughs have occurred once in the last 35 years while ten percent furloughs have occurred twice in the last 25 years. Neither occurred while we were retiring 3-4% per year with annual retirement percentages of 6-7% about 4 years away.
