SunExpress (XQ)

SunExpress (XQ/SXS) is a low-cost carrier based in Turkey, founded in 1989. It operates from its hubs at AYT and ADB, where much of its connecting network is built.

It operates independently of the global airline alliances, so its flights are generally sold as standalone point-to-point tickets rather than as part of an alliance network — something to keep in mind if a journey needs connections on more than one airline.

As a low-cost carrier, its headline fares typically cover the seat itself, with extras such as checked baggage, seat selection and onboard food and drink commonly priced separately. Read exactly what your chosen fare includes, and add any bags online in advance, since paying at the airport is usually more expensive.

When flying SunExpress, book under the airline code XQ, check the carrier's current baggage, check-in and travel-document rules on its own website, and allow enough time at AYT and ADB if you are connecting.
