Here on the runway at San Francisco International Airport, the travel possibilities are practically endless, thanks in part to early innovators in aviation, whom we honor today for National Aviation Day (three cheers for the Wright brothers!). Even if you don’t leave the runway, this airport is a destination unto itself. It’s home to its own museum, with a permanent collection on aviation history as well as rotating art, history, and video exhibits. If that’s not your thing, find your inner peace in the airport yoga room, or keep an eye out for the ‘wag brigade,’ a team of airport dogs on hand to boost the moods of travelers.
