Five USA airports with a Centurion Lounge, but no Priority Pass lounge: Denver, Los Angeles, New York LaGuardia, Philadelphia, Phoenix.
Eight USA airports with an Escape Lounge (aka Centurion Studio), but no Priority Pass lounge: Bradley, Greenville Spartanburg, Oakland, Palm Beach, Phoenix, Providence, Reno, Sacramento.
One USA airports with a Plaza Premium Lounge, but no Priority Pass lounge: Newark (Many more if we were to include Canada.)
Some of these would have restaurants ar other facilities that accept Priority Pass, but not a lounge.
Wow, thanks. That is more than I was thinking.
