The Oakland International Airport used to be a very sleepy airport. Then came Southwest and AirTran and the discounters have the airport humming so much that plans are being laid to build a third terminal for the facility.

Among long-term plans for the airport is a new runway that could handle commercial jets at the airport’s South Field. The plan calls for the possibility of building such a facility between 2015 and 2025, citing environmental constraints and funding limitations as reasons why the runway would be impractical any sooner.
Passenger traffic has increased dramatically at the airport over the past decade. Oakland’s major carriers — discounters Southwest Airlines (NYSE: LUV) and JetBlue Airways — are among the industry’s most successful. The airport reached an all-time high of 14.4 million passengers in 2005.  via East Bay Business Times
