Frontier was previously purchased by Republic in 2008 when we were in bankruptcy. The purchase of Frontier (F9) was closed in December to Indigo Partners (former majority owners in Spirit, plus many other airlines, and headed by Bill Franke, formerly CEO of America West). F9 pilots are a seperate pilot group. There is documented IMSL (Integrated Master Seniority List) from the period of time that Frontier pilots were considered under the same roof as the Republic regional pilots, but no transfer of pilots into F9 pilot group has ever been awarded from this list; however it's an ongoing, ridiculous, and long story. Hopefully soon the NMB will grant F9 single carrier status and the existing Teamster union representation will be thrown out and we can stop talking about it.
