(WARNING: math in public)
Assumptions:
1) UAL will grow to 15,000 pilots in 5 years
2) The current junior pilot is ~12,500
3) UAL will experience ~500 retirements per year
Yes, and very theoretically, a new hire
could be 10,000 out of 15,000 in five years placing him/her @ 67% and within the range of the most junior captain seat.
BUT ---if history is any indication--- no five year forecast in the airline business is ever accurate. SOMETHING always happens that changes the dynamic.
UAL could buy E190s and we could have three year captains based strictly on low pay and poor schedules.
Age 67 (or 70 or 75) could happen.
The regional pilot pay shortage could get fixed.
FO flight time minimums could get lowered thus helping the regional pilot shortage.
War could occur (again).
Oil prices could collapse....or double...or triple.
UAL could experience another merger.
The US economy could slide into another major recession.
There could be another successful terrorist attack against civilian aviation.
UAL could grow to a 17,000 pilot airline in five years.
The list is endless. The only constant is change. Ask a LUAL '97 hire that was a captain in 2000 or a LCAL '05 hire that was a captain in 2009 how fast things can change.
All one can do is get a seniority number and enjoy the ride....because it WILL be a ride with alternating periods of growth, stagnation, and backward movement over a 30 year career.
