These operational notes prefer the structured airport facts snapshot, then fall back to the accepted airport reference at sanantonio.gov, then blend that with local timezone, route, and city-access data already on this page.
Decision matrix for SAT
These are the specific situations where this airport page earns its keep: time-zone conversion, city transfer planning, nearby airport backup logic, and source-confidence checks before acting.
When the clock matters
SAT uses America/Chicago (CDT, UTC-05:00). Use this before overnight arrivals, cross-date departures, and same-day connections.
When surface access matters
San Antonio International Airport is about 12 km from central San Antonio; build that transfer into arrival and check-in planning.
When alternates matter
AUS Austin is the closest retained alternate at 107 km, time difference +0h.
When source checks matter
sanantonio.gov is listed as the official airport website in the airport facts snapshot; live schedules, gates, routes, terminals, and NOTAM-sensitive operations still need official airport or airline verification.
How this airport compares nearby
These comparisons place SAT inside the retained airport graph by country, timezone, elevation, and coordinate neighbors. They are deterministic dataset facts, not generated flight claims.
Country-rank position
SAT ranks #77 in the curated United States airport set when large airports are listed before medium airports, then sorted by IATA code. The retained country set has 94 airports.
Same-zone airport cohort
SAT shares America/Chicago with AUS Austin US · BHM Birmingham US · BNA Nashville US · DAL Dallas US · DFW Dallas-Fort Worth US · DSM Des Moines US. This helps separate same-clock airports by city, country, code, and geography.
Elevation-neighbor cohort
