So listening to NPR yesterday, they were talking about allowing Cell Phone use during flight. Personally I'm against this, when I fly I like the white noise lulling me to sleep while I sip a Gin and Tonic. Personally I feel this is too close to be around people who are hashing things out with their SO, talking business, or just gabbing to pass the time.
This Planner's Opinion: Put the phone away and wait till you land (which it used to mean off the plane. I took a flight three weeks ago and someone's phone was out as soon as we touched the ground )
