Turkish Airlines has unveiled a number of new functions on the airline’s app, alongside new business class headphones.

Through the app, passengers can now add flights, cancel reservations, reissue tickets, add infant passengers and upgrade to business class. It will also offer maps of major airport terminals around the world and driving directions to these airports.

The carrier has also updated its in-flight entertainment offering to include noise-cancelling headphones from audio manufacturer Denon.

Business class passengers on the carrier’s American routes will be able to use the headphones, while passengers in other classes can purchase them on the airline’s online marketplace, Shop and Miles.

Business class passengers on short-haul flights without personal rear-seat screens will also be offered Samsung Galaxy S2 tablets to access the airline’s in-flight entertainment.
