Emirates Airline (EK) signed a three-year sponsorship deal with Lisbon's football club Benfica in May 2015.

Under the sponsorship deal, Emirates will have its "Fly Emirates" logo on Benfica's jersey until the end of the 2017-18 season.

On Oct. 25, the derby day between Sporting and Benfica, the official sponsor Emirates led a group of flight attendants to the center of the field and gave a special "safety video" instructions in front of about 65,000 fans.

Emirates already sponsores Arsenal in the English Premier League as well as AC Milan in Italy's Serie A, Real Madrid in Spain's La Liga and Paris Saint-Germain in France's Ligue 1.
