Yup — this was the scene at San Francisco International Airport the morning of Friday, May 8. Looks like the flying public and airlines have abandoned SFO? Over 57 million passengers a year pass through SFO — that equates to 460,000 airport operations (in and outbound flights) a year — last year over 4 million travelers made their way through SFO. The flying business has no where to go but up up and away!!!
