The 717 Captain seats were protected until 2015 and then would only have been filled by vacancies created by retirements--i.e. no bump and flush. If the 717's go to Delta as announced it will create about 300 more Captain upgrades since AT pilots can not bid for SWA left seats until 1 Jan 2015. When they can bid over it will be to fill positions opened up by retirements/growth--again no bump and flush.
