SFO has no line for business class or high status travelers. (they have pre and clear).
That's the only difference.
That's the only difference.
It’ll also usually be branded “priority” or “premium” with the dominant airline for that airport/terminal (eg. Sky Priority or Premier Access).
Large airports like SFO, DEN and LAX have all combinations of CLEAR/PreCheck/Premium. Smaller ones only have some (ie. premium line doesn’t have precheck or clear).
The only airport I’ve been to recently that I don’t recall having a line like that was Bozeman.
Terminal 3 definitely has a United “Premier Access”/Star Alliance Gold line.
I never use it, though... the pre check line is usually as fast or faster.
