Oman Air (Arabic: الطيران العماني‎‎) is the national airline of Oman. Based on the grounds of Muscat International Airport in Seeb, Muscat, it operates scheduled domestic and international passenger services, as well as regional air taxi and charter flights. Its main base is Muscat International Airport. Oman Air is a member of the Arab Air Carriers Organization.

Oman Air can trace its root back to 1970, when Oman International Services (OIS) was established. The company became a civil aircraft ground handling provider at Beit Al Falaj Airport. In 1972, OIS moved its operations to the new terminal at Seeb International Airport. The company took over Gulf Air’s Light Aircraft Division in 1977, before establishing Aircraft Engineering Division in the same year. Rapidly expanding civil aviation industry of Oman led OIS to the building of several facilities – including hangars, workshops and in-flight catering – to cater for the increase in activity.

In 1981, Oman Aviation Services became a . OAS also purchased 13 aircraft from Gulf Air, allowing the company to replace its turboprops Fokker 27-600 with the −500 series. The following year, Oman Aviation Services jointly commenced jet services, along with Gulf Air, to Salalah. From 1983 to 1993, the company purchased new equipment, including the Cessna Citation, and new facilities to help it improve its services.

In 1993, Oman Air was founded. The airline's start was in March, when a wet-leased Boeing 737-300 from Ansett Worldwide Aviation Services (AWAS) flew from Muscat to Salalah. In July of the same year, the airline's first international flight was operated to Dubai, also using a Boeing 737–300. Flights to other destinations quickly followed, with Trivandrum (Thiruvananthapuram) services starting in November, Kuwait and Karachi in January 1994, and Colombo in October. In 1995, two Airbus A320s were wet-leased from Region Air of Singapore to replace the 737s. From 1995 to 1997, services were commenced to Mumbai, Dhaka, Abu Dhabi, Doha and Chennai. In October 1998, Oman Air was admitted in the international aviation industry trade group International Air Transport Association (IATA). By the end of the following year, Gwader, Peshawar, Jeddah and Al-Ain were included in the airline's ever-expanding route network, although the former two, along with a host of other destinations, were withdrawn in 2000.
