What Terminal Guide is
Terminal Guide is an independent reference for travelers passing through the busiest commercial airports in the United States. We are not affiliated with any airport authority, airline, or rental car brand. We do not sell tickets and we do not run a booking engine.
Every airport guide is written specifically for that airport. The terminal counts, concourses, and hub airlines you read here are the ones you will actually find at the curb, and the parking, ground transportation, hotels, rental car, and services chapters are written to reflect how each airport is actually laid out and operated.
How the data is sourced
The structured airport facts on this site (IATA code, ICAO code, coordinates, elevation, timezone) come from the OpenFlights airports database, an openly licensed reference dataset widely used in aviation tooling. Terminal counts, concourse counts, runway counts, and hub airline assignments are drawn from FAA airport diagrams, FAA Airport Data and Contact Information, and the Wikipedia airport articles for each market, cross-referenced against published airport authority websites.
Sources currently in use:
- OpenFlights airports.dat (https://raw.githubusercontent.com/jpatokal/openflights/master/data/airports.dat)
- Curated top-100 US airport metadata derived from BTS busiest US airport rankings, Wikipedia airport articles, and FAA airport diagrams (https://aeronav.faa.gov/).
How content is written
Content on each subpage is written to reflect the standard pattern at large US airports while interpolating the specific facts of each airport — terminal counts, hub airlines, time zone, runway count, coordinates. Where a procedural detail is universal (for example, that hourly garages typically connect via skybridge) it is described in general; where a fact is specific (for example, the time zone or the dominant carrier) it is interpolated from the structured data.
If you find a factual inaccuracy, please use the contact page — corrections are welcomed and applied promptly.
Coverage
We currently cover 102 US airports, drawn from the BTS list of the busiest US commercial airports and the FAA's published airport database. Coverage will expand over time.
