That's always a wise plan. However many airlines don't like (or tolerate) "dual citizenship" so to speak, so tread very lightly trying to finagle leaves/vacation/etc or otherwise trying to hedge your bets. If you go, just commit and go.

This may be a good time to revisit LOA 19 (I think) and formulate a plan for flow downs. Contrary to the bathroom wall sea lawyers, it doesn't seem like there's anything in that LOA stipulating the flow down was ever repealed with any status change with CPZ. If the company furloughs, it seems like they are still under the obligation to provide for the job equivalent of the number of large RJ's that the same LOA provided for in the first place based only off of the flow down protections. IOW, if they furlough, they'll have to park 30ish large RJ's unless they provide flow down opportunities at up to year 4 pay IOW the very LOA that allows that number of large RJ's to exist at any airline.
