As part of Dutch carrier KLM's Book Mobile, Stay Mobile! campaign, all travellers who book their flights through the airline's mobile application or mobile site will receive a free external battery.
The campaign, which runs until Dec 24, encourages travellers to access the airline's new mobile site and app for hassle-free booking. To take part, travellers must go to KLM.sg or launch the app on their phones to book their flights. The airline will then deliver the battery to their homes, free of charge.
