Airport index methodology

How we calculate this: Airports are grouped by country code, then sorted with large airports first and named airports alphabetically inside each type. Local time uses each airport’s stored IANA timezone identifier. Passenger figures, hub-airline tags, and operational facts come from the per-airport curation file when available; absent figures are left blank rather than estimated.
Data sources: OurAirports for IATA/ICAO, coordinates, elevation, and airport type; IANA Time Zone Database for local-time rules; airport-shaped Wikipedia summaries for the curated facts file (passengers, runways, terminals, hub airlines, operator, year opened); hand-curated country dossier sources (FAA, CAAC, DGCA, Rosaviatsiya, IATA, national civil-aviation authorities) for the editorial dossier block where present; curated country records for country names and locale-safe slugs.
Update cadence: Airport country pages revalidate weekly. The OurAirports source CSV was last fetched 2026-04-25; the airport-facts snapshot was last generated 2026-05-21. This page currently represents 1 large airport rather than a complete national aviation registry.

Content reviewed Apr 30, 2026. This airport index is reviewed as a curated reference surface. It does not claim complete aviation coverage for Singapore; it lists 1 retained airport record (1 large airport) across Asia/Singapore.

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.

Country airport evidence

Why this Singapore airport page is retained

12/12 signals

This page is classified as a single-airport reference. 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

single-airport reference

Singapore has 1 retained large/medium airport record (1 large, 0 medium) across 1 IANA zone.

Code and entity coverage

1 IATA, 1 ICAO

1 retained record have airport-facts rows; 1 cite official airport domains and 1 carry Wikidata entity links.

Traffic and operation facts

1 passenger rows

1 records quote passenger-volume facts; 3 runway counts are aggregated where quoted; 1 records carry scheduled-service flags.

Timezone pattern

single airport-timezone cluster

The retained airport set resolves to one dominant local-clock pattern, but each airport still stores its own IANA identifier for DST-safe calculations.

Verification boundary

6 source URLs

Visible source hosts include changiairport.com, en.wikipedia.org, wikidata.org, ourairports.com. These support identity and static facts, not live routes, terminal assignments, NOTAMs, or airline schedules.

How to use Singapore airport data without overreading it

Country-specific caveats

Start with the gateway layer

Singapore Changi Airport (SIN) is the first retained airport to check for Singapore; then scan the 1 large and 0 medium records for regional alternates.

Keep airport-local time explicit

The retained airport set behaves like a single local-clock cluster, but the airport-specific IANA zone still matters around DST transitions and imported calendar events.

Use codes for the search, city pages for context

1 airport records link onward to vetted city-time pages, so a code lookup can become a local-clock, daylight, holiday, and meeting-time check.

Treat schedules as live elsewhere

1 retained record carry a scheduled-service flag, but route availability, airline service, terminals, and disruption notices are not live here.

Watch holidays and local operating days

Singapore has a holiday country page on this site, so use it alongside airport time checks for closures, public-holiday pressure, and ground-service planning.

Know what the passenger data covers

1 retained airport quote passenger-volume facts. Airports without a quoted figure are not ranked by traffic on this page.

Airport coverage patterns

How the Singapore airport index is structured

This page adds country-level context around airport counts, code coverage, timezone spread, and city-clock handoffs. It is built from the retained airport dataset rather than a live airline or aviation registry feed.

Coverage pattern

Singapore has a single retained airport record (1 large airport). With one entry, this page is effectively a single-airport timezone reference rather than a country-wide index.

Code reliability

Every retained Singapore record carries both an IATA and an ICAO code (1 of each), so passenger-facing and aviation lookups resolve consistently across the set.

Timezone spread

Every retained airport in Singapore resolves to Asia/Singapore (1), so the country's airport clocks move together and a single offset check covers the whole set.

Major airport examples

The standout anchor here is Singapore Changi Airport (SIN) in Singapore. Large airports lead the list because they are the most reliable hooks for travelers, city clocks, and cross-border time checks.

City-clock handoff

Airport records here hand off to indexable city pages such as Singapore (SIN). Handoffs are restricted to vetted city pages so the airport index does not spend crawl budget on thin local URLs.

Busiest airport

Singapore Changi Airport (SIN) in Singapore at 70 million passengers sits at the top of the curated passenger ranking for Singapore. Curated passenger figures are attached to 1 retained record on this page. Aggregated curated annual passenger volume across those records is 70 million. Numbers come from the airport-facts curation file and reflect the latest year quoted there, not a live traffic feed.

Regional peer comparison

Singapore has 1 retained airport records vs. Afghanistan 1, Azerbaijan 1, Hong Kong 1 in the same continent. This is a structural comparison of retained-record counts, not an audit of national aviation policy or fleet size.

Operational depth

Across the retained Singapore set we have 3 curated runway records, 4 curated terminal records, and 1 airport flagged with scheduled service. Operational facts come from the Wikipedia-derived airport-facts curation, which is sparse for smaller airports and not a substitute for the airport authority's own data.

Editorial dossier

Changi Airport (SIN) handled 67.7 million passengers in 2024 (+14.8%) — 99.1% of the 2019 peak. China, Indonesia, Malaysia, Australia, and Thailand were the top source markets. Singapore Airlines, Scoot, and Jetstar Asia dominate; Changi connects to 158 cities through 100+ airlines. The CAAS regulates; Changi Airport Group operates the airport. Terminal 5 construction targets a 2030 opening and 50 million annual capacity addition.

Traveler boundary: use these records for timezone orientation and airport discovery. Verify live operations, route availability, terminal status, and NOTAM-sensitive details with official airport, airline, or aviation sources.

Time-zone span

Single-zone airport clock for Singapore

All retained airport records resolve to one IANA timezone (Asia/Singapore, UTC+08:00 SGT no DST). Local-clock math is simpler here than in multi-zone countries, but the airport’s stored IANA identifier is still the authoritative reference for DST transition weekends.
