(Oakland=OAK) Under normal weather conditions at OAK, operations favor using Runway 29 at the South Field and Runways 27R & 27L and the North Field. The only change to this is usually only in the winter when weather fronts move through the area. Then they use Runway 11 at the South Field and Runways 9L & 9R at the North Field.
