Zabol Airport — Zabol, Iran

Zabol Airport, in Iran's Sistan and Baluchestan Province near the border with Afghanistan, runs a single runway at 1,628 feet above sea level, out in the country's remote southeast. Scheduled air service here stays modest in scale, matching a province that is Iran's largest by area but one of its least densely populated. Zabol itself sits in a region known for strong seasonal winds sweeping across flat terrain. A faster connection to Tehran and other major Iranian cities is the field's main value, replacing what would otherwise be a very long overland route across the province.
