SCOPE!!!!

it allows a higher MTOW for 50 seat RJs, which in turn allows them to reconfigure CRJ700s to 50 seats to replace aging and passenger hated -200s and E 145s. The CRJ550 is extremely operationally limited at 65,000 MTOW. This TA raises MTOW to 69,XXX

it also allows the company to assign reserves earlier on day 1 (6am I think)
