Air traffic used to be everything flew to places local to it but now there's a system of hubs, Chicago O'Hare for instance or Newark where planes fly through.
There's no minimum service, customers are allowed to change their plans on the fly, and there's even a handy parental control mode that lets concerned caretakers set curfews and app restrictions on their kid's phones.
Not surprisingly, elements that demand a truly big screen or a windowed interface won't fly -- there's nowhere to drag-and-drop from or open a new window to.
