The Jin Air OSL took quite a while to start after the 2010 Bacchus OSL resolved. Officially, the broadcaster, OnGameNet, started an amateur league named "My Starleague" that ran for the period, with the winners of each regional league to be able to participate in next OSL offline preliminaries. However, the real reason might have been the ongoing controversy between KeSPA and Blizzard, which was eventually settled. There were also rumors that the OSL start was delayed because they had some difficulty getting sponsorship. Jin Air is a subsidiary of Korean Air, which already sponsored two Starleagues, namely Korean Air Starleague 2010 and Korean Air Starleague Season 2.
The Jin Air OSL saw the Legend of Fall materialize once again after Incruit OSL as JangBi beat Fantasy in the Finals.
The Jin Air OSL saw the return of the OGN Dual Tournament (ODT) instead of the Ro36 used in the Starleagues before.
