Some airports don’t have any lounges (Denver, Philly, San Diego, & more) that participate in the Priority Pass membership that several credit cards offer for free.

San Francisco International Airport has one, and it’s hidden from the majority of travelers, tucked away in the international terminal.

Priority Pass members can only access the lounge if flying out of the international terminal’s Concourse A.

But if you’re flying JetBlue like I did this weekend, you’re in luck, because JetBlue uses international terminal Concourse A.

Quick review:

Pros: Awesome espresso machine, self-serve liquor bar, nice views, tons of high-quality food and seating options. And addicting marble brownies.

Con: Only accessible if you’re flying international, or on JetBlue, Alaska, or Hawaiian.
