I do appreciate the CommutAir info...
From CLE, ORD is hourly with lots of mainline... EWR and IAD have less frequency and a fraction of the capacity...There's a lot more market to ORD. Strangely enough, not a close comparison in terms of commuting.
With zero 121 experience, no matter how you cut it, the upgrade is 1000 hours away...which is about two years at most regionals when starting out? Even if seniority would allow insanely fast upgrades sooner, it ain't gonna happen...not complaining, just observing...
