San Francisco International Airport (SFO) is suing the recently renamed San Francisco Bay Oakland International Airport (OAK) over the use of the name ‘San Francisco’. The lawsuit has been met with a counterclaim from OAK, insisting that the name change accurately describes its geographic location. Both airports are located near San Francisco Bay, but neither of them is actually in San Francisco. The dispute highlights the potential for confusion among travelers and the competition between the two airports.
