With the Interline/SPA agreements, Turkish Cargo expands its network area and can serve destinations that are not served on their own. Turkish Cargo currently has 160 interline agreements and more than 80 SPA agreements with other airlines, and this number is increasing day by day. These agreements would allow airlines to serve their customers on a wider network. The internal market was deregulated in 1996, allowing for new competition between charter airlines. At the same time, major international airlines have created fierce competition on routes to Western Europe. THY has entered into marketing agreements with other international airlines to improve their competitiveness. The company partnered with Japan Airlines in 1997 and 1998 to engage Osaka and Tokyo. Other joint flights soon followed with Austrian Airlines, Swissair and Croatia Airlines.  Turkish Cargo strives to continue its efforts to increase the number of its interline and SPA agreements, in order to meet the needs of its customers in locations where they are outside their own network and to develop better international logistics solutions for their business partners.
