I have a genuine paid F trip coming up. Expedited security is supposed to be included (along with all PDX/GEG tickets), although the official signs just mention MVP Gold. Are the checkers aware of paid F access -- or has that been discontinued?
I haven't had any problems recently with this in SEA -- just go up to the clerk and politely show them your F ticket. But it's definitely variable -- other airports I've been told it doesn't apply.
