I think we're getting closer - at my local airport, no airport employee checks the BP in the first class line - ya just walk right up to TSA. Sounds like the answer is "zero" guaranteed guests, and a YMMV situation for the rest.
My boarding pass always says EP - but it ALSO says "Priority" - as do all boarding passes on my reservation, regardless of status. Now I'm wondering which of these words got me thru the 1st class line - as
mentioned, seems unlikely TSA is keeping up with the elite status nomenclature of all airlines...
Thanks everyone!
