See if you can get a copy of both union agreements and the write down the work rules/Regs/trip duty/etc and try to compare apples to apples.
Example Republic has a minimum duty guarantee of 4.2 hours.
Compare that to ENDV
What that means is, you are on reserve, you get called because an F/O is sick. So you finish his/her trip.
You fly JFK-Buffalo (that is ballpark a 1 hr flight)
You spend the night in the hotel at Buffalo then fly the next day Buffalo to JFK (another 1 hr flight). Then you go home after that leg.
Your total flight time is 2 hours. At Republic you get paid credit of 8.4 flt hours (4.2 for each day). At other airlines that don’t have a min trip duty guarantee, you get paid 2 hours. So granted RPA pays less per flt hour, but you just made 6.4 hours of FREE MONEY
Someone from ENDV can chime in on all their work rules and duty rigs. These contractual rules are VERY IMPORTANT if both airlines have a base you want to live. Now Endeavor advertises they will Positive Space Pilots to work, so commuting wouldn’t be an issue. If you do choose to commute, this benefit is HUGE.
