Here we go - from the 2005 10K found in the March 2006 SEC filings:
In connection with the ASA acquisition, we have established new, separate, but substantially similar, long-term fixed-fee Delta Connection Agreements with Delta for both SkyWest Airlines and ASA. We also obtained control of 26 gates in the Hartsfield-Jackson International Airport located in Atlanta, from which we currently provide service to Delta. Delta has committed to provide to us opportunities to utilize 28 additional regional jets in our fleet by the end of 2007. Delta has also agreed that, starting in 2008, ASA is guaranteed to maintain its percentage of total Delta Connection flights that it has in 2007, so long as its bid for additional regional flying is competitive with other regional carriers.
So ASA is guaranteed an overall percentage of DCI flying but still nothing specific (20-25% maybe?) and not necessarily 80% out of ATL. Anyone know where the 80% number comes from (or did someone just pull it out of their arse?)
Potential Opportunities from Delta’s Restructuring. We believe that as Delta restructures its fleet under bankruptcy protection, there may be new regional flying contracts that become available for qualified regional carriers. ASA holds certain rights to maintain its proportion of overall Delta regional flights, as well as its proportion of Atlanta regional flights. This may help ASA compete for new flying mandates, if any, that come into existence at Delta.
SA uses 26 gates at the Hartsfield-Jackson Atlanta International Airport: 13 gates are leased directly from the airport authority, six gates are subleased from US Air, five gates are subleased from Delta and two gates are used pursuant to a month-to-month arrangement. ASA intends to lease from Delta three additional gates effective December 1, 2005.
