Furthermore, there is probably not a route from EWR which COEX cannot fill up a 37-seat ERJ... So having 19-seaters at EWR is a complete waste.
As for expansion in the event of a US Airways failure... There are SAAB SF-340's out there for the taking, and Commutair (as CO Connection) could probably offer some point-to-point service from BOS (like BOS-BUF/ROC/SYR), maybe LGA/DCA if slots are cheap. There also may be additional opportunities from CLE as PIT shrinks. I know Commutair/CO Connection applied for (but was bot selected) some EAS markets from CLE which are currently service via PIT. As PIT shrinks, maybe Commutair's case going forward becomes stronger.
