Most easyJet flights are short enough that you can usually stave off boredom with a book and an expensive beer, but in-flight entertainment could soon be part and parcel of your airfare. Instead of retrofitting planes with seatback screens, easyJet is going down the increasingly popular route of launching a bring-your-own-device entertainment service. Connect your phone or tablet to the plane's WiFi network, point your browser at the Air Time portal and you'll have access to TV, films and audiobooks for adults and kids alike.
