Turkish regional operator, Borajet, announced in late April that it will be suspending operations due to the lack of serviceable aircraft. The airline stated it was experiencing a shortage of operational aircraft after spare parts could not be sourced for six of the Embraer aircraft. As a result, the current schedule could not be maintained with only four aircraft and therefore services were suspended on the 24th of April and will not resume until 2018. Fellow Turkish airline; AnadoluJet will perform flights for Borajet passengers until June 2017.

Indonesian budget carrier, Lion Air, has been cautioned by the State Ministry of Transport (MOT) due to a number of operational concerns and mistakes. The MOT has given the airline two months to improve its operational conduct or be faced with sanctions and fines. The airline has reportedly committed a number of operational errors and breaches of conduct, including aircraft departing without all passengers, regularly delayed flight services, incorrect passenger manifests and an instance of a Boeing 737 aircraft leaking fuel onto the tarmac whilst parked in gate.

Güneş Ekspress Havacılık A.Ş, Operating as SunExpress, is a regional operator based out of Antalya Airport, Turkey. The airline was launched in 1989 as a joint venture between state carriers Lufthansa and Turkish Airlines, each of whom retain a 50% stake. Operations commenced the following year, in the form of a charter flight between Antalya and Frankfurt. Shortly after, scheduled flights were launched with a small fleet of Boeing aircraft.

Since its inception, SunExpress has undertaken significant growth of its fleet and route network and now offers services to many Turkish and regional destinations. During March 2010, SunExpress took over the first of several AnadoluJet aircraft and commenced operating on behalf of AnadoluJet. It is important to note that AnadoluJet does not have its own individual Air Operating Certificate (AOC). The airline's operations are almost exclusively undertaken by SunExpress under the operating license of SunExpress. In 2011, SunExpress, launched its sister subsidiary airline, SunExpress Germany (Deutschland GmbH). This airline operates under its own Air Operator’s Certificate and is classed as a separate entity.

In early 2017, SunExpress operated a young fleet of Boeing 737 series aircraft with an average age just over five years. Furthermore, the airline has placed orders for an additional 37 aircraft, indicating it likely has access to sufficient financial resources.
