Detailed data
Nightly
Reference airport. The tower here is staffed 24 hours. The hours above are the airport's own published quiet hours, when the passenger airlines have agreed not to schedule flights — a voluntary agreement, not a federal rule. We watch these nights so they can be compared with airports whose tower is closed; they are not counted in the site's totals. See all airports
