While public showers are not a standard feature in all US airports, they are available in several major international hubs, though they are almost always a "pay-per-use" service or restricted to lounge members. Airports like San Francisco (SFO) offer the "Freshen Up!" facility in the International Terminal, where you can rent a shower room for a set fee (usually around $25–$40). Other airports like Dallas/Fort Worth (DFW) and Miami (MIA) have showers located within "Minute Suites" or specialized spa areas. The most common way to find a shower is through airline lounges (such as United Polaris, Delta Sky Club, or American Admirals Club), which require elite status, a premium ticket, or a high-end credit card for entry. For the general public without lounge access, searching for "airport transit hotels" or spas is the best bet. Interestingly, smaller regional airports in the US almost never have shower facilities, as they are designed for quick turnarounds rather than long international transits.
