CAS, which was founded as a partnership between Cyprus Turkish Airlines and Havaş with 50 percent shares, has been providing ground handling services at Ercan Airport since August 2008.

Havaş participates in 32.4 percent of TAV Gözen Havacılık ve Ticaret A.Ş., which was founded by Havaş, Gözen Havacılık and Türkmen Havacılık in June 2008 in order to provide hangar services for private jets at Istanbul Atatürk Airport, and the company is planned to be operationally active in the second half of 2009.

Turkish Ground Services Company, 50 percent of which belongs to Havaş, was established as an extension of the philosophy to organize and carry out Turkish Airlines ground handling services under the roof of another company.

As a result of a negotiation which has started at the last quarter of 2009 Havaş and Baltic Aviation Systems (BAS) agreed on being partners in North Hub Services (NHS) by Havaş buying %50 shares of NHS from BAS. NHS, which is head quartered in Riga-Latvia, has started providing passenger services to Air Baltic flights as of 01.01.2010. After the partnership is registered, NHS won the tender for Ramp License that will allow it to provide ramp handling to 3rd parties in Riga Airport.
NHS, as a member of International Aviation Handlers Association (IAHA) and IATA Ground Handling Council (IGHC), has the mission of supporting its customers with a high standard ground handling service and the vision to be the No.1 ground handler across Northern Europe. NHS is now providing representation, supervision and administration, passenger services and aircraft services to its customers.
