Country airport index
This page lists 94 retained airport records in our curated United States airport catalog with IATA and ICAO codes, city names, and local timezone information. Airport records come from OurAirports and timezone rules come from the IANA database. Click any airport for coordinates, elevation, the current local time, and nearby airports.
Content reviewed Apr 30, 2026. This airport index is reviewed as a curated reference surface. It does not claim complete aviation coverage for United States; it lists 94 retained airport records (94 large airports) across 11 IANA timezones (America/New_York, America/Chicago, America/Los_Angeles plus 8 more).
Coverage note. This is an airport-reference index for timezone and travel planning. It focuses on retained large and medium airport records with usable codes and coordinates, not every runway, heliport, closed facility, or local landing strip. Airport service levels, terminal operations, route availability, and codes can change; verify with the airport, airline, NOTAM, or official aviation source before travel.
Timezone note. Airport timezone records can be more granular than the country profile. America/Boise, America/Detroit, America/Indiana/Indianapolis, America/Kentucky/Louisville appears in the retained airport records but not in the country-level timezone list, so use the airport record for local-time calculations.
Country airport evidence
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.
Retained scope
multi-zone gateway network
United States has 94 retained large/medium airport records (94 large, 0 medium) across 11 IANA zones.
Code and entity coverage
94 IATA, 94 ICAO
94 retained records have airport-facts rows; 94 cite official airport domains and 94 carry Wikidata entity links.
Traffic and operation facts
12 passenger rows
12 records quote passenger-volume facts; 284 runway counts are aggregated where quoted; 94 records carry scheduled-service flags.
Timezone pattern
11 airport zones
Airport clocks span UTC-10:00 to UTC-04:00, so this country page must keep airport-local time rather than assuming Pacific/Honolulu.
Verification boundary
391 source URLs
Visible source hosts include abqsunport.com, en.wikipedia.org, wikidata.org, ourairports.com, albanyairport.com, dot.alaska.gov, atl.com, ci.austin.tx.us. These support identity and static facts, not live routes, terminal assignments, NOTAMs, or airline schedules.
Editorial status

Manual dossier sources are attached for country-level aviation context; point-in-time statements still defer to the linked authorities.

Traveler planning patterns
Orlando International Airport (MCO) is the first retained airport to check for United States; then scan the 94 large and 0 medium records for regional alternates.
Do not assume one country clock: retained airport zones span UTC-10:00 to UTC-04:00. That matters for overnight arrivals, missed-connection buffers, and airport pickup times.
29 airport records link onward to vetted city-time pages, so a code lookup can become a local-clock, daylight, holiday, and meeting-time check.
94 retained records carry a scheduled-service flag, but route availability, airline service, terminals, and disruption notices are not live here.
United States has a holiday country page on this site, so use it alongside airport time checks for closures, public-holiday pressure, and ground-service planning.
12 retained airports quote passenger-volume facts. Airports without a quoted figure are not ranked by traffic on this page.

Regional peer comparison
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.
Country aviation dossier

Time-zone planning
For overnight flights, connections near daylight-saving transitions, and cross-border itineraries, use the airport’s IANA timezone instead of assuming every airport follows the country’s primary zone.
Codes, clocks, and city mapping
IATA coverage
94 codes
Useful for passenger-facing flight searches, tickets, airport boards, and quick route lookup.
ICAO coverage
94 codes
Useful for aviation references, flight tracking, weather briefings, and operational documents.
Airport mix
94 large / 0 medium
Gateway airports are prioritized first, but regional airports remain useful for local clock checks.
DST travel risk
Multi-zone
Recheck local airport time around overnight arrivals, daylight-saving weekends, and cross-border connections.
