They can train furloughed sUAL pilots to fly the sCAL current/future 737s indefinitely. Once all the 1457 sUAL pilots have gone through the sCAL 737 schoolhouse and are flying mostly sCAL 737 aircraft, the sUAL SLI committee will have a strong point about UAL being right-sized for a merger--1457 UAL pilots were flying mostly UAL 737s and now they're flying CAL 737s? seems like a plan. Or a shell game.
