Airports in United States.

This page is classified as a multi-zone gateway network. The evidence score comes from static source coverage: codes, airport facts, official domains, city-clock handoffs, IANA zones, operational facts, and country dossiers where present.

These numbers aggregate the curated airport-facts file across this country’s retained records. Missing fields mean the curation file does not quote that figure; they are not zero-imputed.

The rows below show why the top airport records are useful beyond a country list: role labels, code identity, timezone, scheduled-service flags, passenger/runway facts where quoted, and the source hosts that back static airport identity.

United States’s retained airport records span 11 IANA zones from UTC-10:00 to UTC-04:00 — an offset spread of 6.0 hours. At least one zone observes a seasonal DST shift, so local-clock math around the transition weekend needs care.

These ranks reflect passenger volumes quoted in the curated airport-facts file; airports without a quoted figure are excluded from this card even if they may be locally busier.

Peers are picked by geographic proximity (same continent) and similarity of retained-record counts. Comparison is structural — it does not audit fleet size, national aviation policy, or passenger traffic.

The US air-traffic system handled roughly 960 million enplanements in 2024 — about 820 million domestic and 140 million international — according to FAA and BTS data. Atlanta (ATL) processed 108.1 million total passengers, anchoring a network of 11 IANA timezones from Pacific/Honolulu to America/New_York. American Airlines, Delta, United, and Southwest dominate the domestic schedule; New Large Aircraft (NLA) and NextGen ATC modernization are the active long-term regulatory anchors.
