But it may not be true. I think it is probably too good to be true.
I flew out of the SEATAC airport this morning but was unaware of the claims and running a little to late to check it out anyway. If I can catch an early flight back tomorrow and arrive at a decent hour I’ll try to check it out.
Update: I was unable to get an earlier flight and I will be getting in very late. There is a strong suspicion that the story is a hoax and others apparently have already put more research effort into it that I would have been able to.
