The Marine Corps is opening its aviation bonus program to some of its more experienced pilots as the military continues its fight to keep seasoned officers from leaving their cockpits for civilian jobs.

Pilots will be eligible to earn bonuses up to $280,000 starting in 2020 if they agree to keep flying another eight years, Marine officials announced this week. The bonuses target captains and majors who fly the F-35 Joint Strike Fighter, F/A-18 Hornet, AV-8 Harrier, MV-22 Osprey, C-130 Hercules, UH-1 Huey, AH-1 Cobra and CH-53 Stallion.
