Official airport sources
McGhee Tyson Airport is the primary source of truth for the current TYS nonstop network and airport-specific traveler facts.
Sources and verification
How we decide what is true
Flight information changes too quickly to treat every source equally. We use a source hierarchy and separate official route truth from live observations, historical patterns and traveler guidance.

Official airline sources
Airline sources are used when carrier-specific schedules, policies or route details need confirmation.

Live flight-search observations
Google Flights and related live-search data provide current schedule, fare and market context. These observations are dated because they can change.

Our analysis
Airport comparisons, trip-use cases, parking math and decision guidance are our interpretation of verified facts—not new operating facts.
What happens when sources disagree?
We do not silently let one secondary source overwrite official route truth. Conflicts are held for verification. A live observation can be useful evidence that something has changed, but it is not automatically treated as authoritative.
Freshness rules
- Current route status: anchored to the latest official TYS route snapshot and monitored for change.
- Operating days and schedules: treated as live or dated context, not permanent facts.
- Fares: treated as observations or historical patterns, never guarantees.
- Airport operations: parking, pickup, terminal and rental-car information is sourced from current airport guidance.
- Historical launches: preserved as historical facts and not confused with today's schedule.
How automated content is controlled
The content system is instructed to answer the primary question first, use only supplied facts and search evidence, avoid inventing schedules or prices, map factual claims to sources, and pass separate fact, UX and structured-data reviews before publication.
Generated pages must also contain meaningful internal links and a clear parent silo so the site does not become a collection of isolated pages.
