It probably depends on your circle of friends and acquaintances but for at least a decade in text messages and social networks I have seen people use airport designations in place of the city they represent. For example, “Spending next weekend in SEA then staying with friends in MPS before returning home to SFO.” So no, SFO is not only ever unambiguously the airport. I believe the combination of more frequent flying, booking tickets ourselves online (rather than by telephone) and increased communication on devices have combined to result in this quirk of language.
