It looks like American Airlines, at least, disallows anything that transmits intentionally. From their policy at [1]: "Devices with transmitting capabilities may only be used if the transmit capability is turned off and can be verified by a flight attendant" and more specifically about something that's likely to use Bluetooth these days (but who knows how long ago they wrote their policy): "During flight, never use ...a cordless computer mouse" So no specific mention of Bluetooth, but they're within a hair's breadth of it. -- Scott [1] http://www.aa.com/aa/i18nForward.do?p=/travelInformation/duringFlight/onboardTechnology.jsp&anchorEvent=false
