Kish Air (Persian: کیش ایر‎) is an airline based in Tehran, Iran. It operates international, domestic and charter services as a scheduled carrier. Its main base is Mehrabad Airport, Tehran.

The airline was established on December 16, 1989 and started operations in 1989. It is owned by Kish Free Zone Organisation (79%), Kish Investment and Development (11%) and Kish Development and Servicing (10%). It has 303 employees (at March 2007).

To start its passenger operations, after receiving temporary operations permission, the airline leased 2 aircraft (one Tupolev Tu-134 and one Antonov An-24) from Bulgaria Airlines on a wet lease basis. Kish Air received its air operator certificate (AOC) in 1990 after demonstrating its competence to the Civil Aviation authorities, during its first year of operations, thus becoming the first private company to receive its AOC from Civil Aviation of Iran. At this time the company began wet leasing three Tupolev Tu-154Ms from Russian leasing companies, returning the previously leased Bulgarian aircraft. The company also wet leased two Yakovlev Yak-42D aircraft from Russia.

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).

Atmospheric stratification describes the structure of the atmosphere, dividing it into distinct layers, each with specific characteristics such as temperature or composition. The atmosphere has a mass of about 5×10¹⁸ kg, three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. An altitude of 120 km (75 mi) is where atmospheric effects become noticeable during atmospheric reentry of spacecraft. The Kármán line, at 100 km (62 mi), also is often regarded as the boundary between atmosphere and outer space.
