Besides its own ”in-flight” magazine it has reached an agreement with the Visit Heart of England Tourist Board to place its bi-monthly lifestyle magazine, The Heart, on board all duo flights to and from Birmingham. duo currently flies non-stop from 11 European cities including Berlin, Copenhagen, Stockholm and Vienna.
