Air Sinai is an airline based in Egypt that operates both domestic and international flights. Founded in 1982, the airline has grown over the years and is now considered one of the leading carriers in the Middle East.

Air Sinai traces its roots back to 1982, when it was established by the Egyptian government as a joint venture between EgyptAir and the government. The airline was set up as a subsidiary of EgyptAir, with the two companies sharing a common management and marketing structure. The airline's first flight was on October 1, 1982, and it flew a route between Cairo and the Sinai Peninsula.

The airline's fleet initially consisted of a single Boeing 707-320, but in 1985 it expanded its fleet to include two more 707s and a single Boeing 737-200. In 1988, Air Sinai struck a deal with Boeing to purchase two more 737-200s, and also leased two Boeing 757-200s from EgyptAir.

Since its inception, Air Sinai has gone through numerous changes, with the airline's fleet and routes expanding over the years. In 2010, Air Sinai became the first Middle East airline to operate an Embraer E170, which it used to expand its domestic network. The airline also launched a new international route in 2011, linking the Egyptian cities of Hurghada and Sharm El Sheikh with Tel Aviv in Israel.

In addition to expanding its fleet and routes, Air Sinai has also had to respond to a number of incidents over the years. In 1983, one of its Boeing 707s crashed into the Red Sea, resulting in the death of all on board. An investigation concluded that the crash was caused by a technical failure in the aircraft's autopilot system. In 2012, the airline was also subject to a federal investigation by the United States Department of Transportation, after an incident involving a passenger being removed from a flight.

Air Sinai has come a long way since its establishment in 1982. The airline has grown from a single-aircraft operation to a comprehensive network of domestic and international routes. In addition, the airline has had to respond to a number of incidents over the years and has made significant improvements to its safety protocols as a result. With a fleet of 11 aircraft and more than 20 routes, Air Sinai is now one of the leading airlines in the Middle East and is well-positioned for future growth.
