Decision matrix for THR
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
THR uses Asia/Tehran (IRST, UTC+03:30). Use this before overnight arrivals, cross-date departures, and same-day connections.
When surface access matters
Mehrabad International Airport is about 9.7 km from central Tehran; build that transfer into arrival and check-in planning.
When alternates matter
IKA Tehran is the closest retained alternate at 34 km, time difference +0h.
When source checks matter
mehrabad.airport.ir 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 THR inside the retained airport graph by country, timezone, elevation, and coordinate neighbors. They are deterministic dataset facts, not generated flight claims.
Country-rank position
THR ranks #6 in the curated Iran airport set when large airports are listed before medium airports, then sorted by IATA code. The retained country set has 6 airports.

Ground Transport and Nearby Context
Central Tehran is close enough that taxi, ride-hail, and rail or shuttle links are usually the fastest arrival options.
Tehran is the nearest mapped city anchor in the current dataset, which makes it the cleanest companion page when travelers want to switch from airport timing into local city timing.
Mehrabad International Airport has 3 nearby indexed airport alternatives, which makes backup departures and diversion logic part of real planning instead of a theoretical edge case.
Nearby city time anchors
Airport pages are most useful when they bridge into real city clocks. These city anchors are ranked by distance from THR, then shown with their own timezone, local time, and time difference from the airport clock.
