"Starting this summer, United Airlines will include 21 Zune music channels as an in-flight listening option. Passengers will be able to listen free of charge by plugging compatible headphones into their armrest and dialing in the channel of their choice. Channels will be offered commercial-free on both domestic and international flights, with each channel loaded with three hours of unique programming."
Can we assume that Zune music channels will be available only on flights within the USA and not on any international routes?
