Priority Pass is the world's largest independent airport lounge access program, with more than 1,500 lounges in 600 cities across the globe. Unlike a credit card or airline lounge brand, Priority Pass is a paid membership that you bring with you — meaning the same card gets you into a Centurion-branded restaurant credit at SFO one day and an independent third-party lounge in Lisbon the next.
For most U.S. travelers, the practical question is not "what is Priority Pass" but "is it worth it for me?" The answer depends on how you obtained it. If you're paying full retail for a Standard, Standard Plus, or Prestige membership out of pocket, the math gets aggressive: at $469 per year for the unlimited Prestige tier, you need to use the network roughly ten times annually to come out ahead of buying day passes piecemeal at $35 to $50 each. Most casual travelers don't hit that number.
The far more common path is bundled access through a premium credit card. Chase Sapphire Reserve, American Express Platinum, Capital One Venture X, and U.S. Bank Altitude Reserve all include Priority Pass Select, which is a slightly different membership tier than the publicly purchasable plans. Notably, several issuers — Chase and Amex among them — have stripped restaurant credits from their version of Priority Pass over the past few years, and Amex no longer includes the program at all on the consumer Platinum after the most recent benefits refresh. Read your card's current terms.
A few practical tips. First, capacity is the program's persistent weakness; lounges that take Priority Pass during peak banks at busy U.S. airports routinely turn away members. Second, "Priority Pass" can mean very different products at different airports — a beautiful new third-party lounge in one terminal, a restaurant credit at a sit-down spot in another, and absolute nothing in a third. Third, most issuing cards include one or two free guests; some have switched to a flat per-guest fee instead. Always check before assuming your travel companion will get in for free.
Worth it? For frequent flyers connecting through major U.S. hubs without an existing airline lounge membership, yes — particularly if you can stack it on top of an Amex Centurion or Capital One Lounge access from the same wallet. Less so for occasional travelers who fly mostly nonstop and are unlikely to use the network more than two or three times a year.
