My displacement WAG:
100% of MD88/90 pilots
15% of ER (mostly on the FO side)
ATL717B will carry pre-furlough excess

BONUS WAG: August - partial cancellation announcement and AE - cash bleeding has stopped and forward looking numbers justify slowly unpausing planned NB deliveries. NYC220B is the big growth category, with more senior 717Bs escaping NYC (and the rest of the system) for systemwide vacancies to support 321NEO deliveries. More junior MDs to 717 have no seat lock, but lack seniority to escape the TYS overnights stacked between 4 leg days shuttling between hubs and everywhere they hope not to layover.
