Turkish Airlines, the national airline, has extended its sponsorship of World Archery, the sport's governing body, until the end of 2015.
Under the terms of the two-year renewal, Turkish Airlines will remain as the official airline of the federation.
For the first time since the two organisations teamed up in 2006, athletes, staff and officials travelling to World Archery events will be permitted an additional 12kg of luggage allowance for their equipment.
Ugur Erdener, the Turkish president of World Archery, said: "We are extremely thankful to Turkish Airlines for its continued support of not only our federation but our athletes, officials and staff that travel worldwide to events."
Turkish Airlines' previous two-year sponsorship deal with World Archery expired this year.
Other official partners of the federation are sportswear brand Fila, watchmaker Longines, Kia Motors and Spor Toto, the state betting organisation in Turkey.
