Quick/easy question. What major airports (major meaning LAX, JFK, LHR, etc) have public use showers in them?? I'm not looking for ones that are in FF clubs/lounges, but ones that you can just pay to get into without any sort of FF status or affiliation.
The only one I know of off the top of my head is in NRT's terminal 1, there is a shower room where you can pay $5 USD for 30 minutes. Does anyone know of any other airports that have a similar offering??
