I take mine on every flight !
However mine will transmit but I have that feature turned off of course, the only thing you have to look out for is the flight attendants because if they catch you the fun is all over for the rest of flight
The trick I use is to have the ear piece towards the window and the radio tucked along my side keeping a close eye on those darn FAs LOL
I remember one time I got caught I must have looked so sad that the flight attendant came back to my seat and asked me if I would like to come up to the cockpit and meet the captain............. man I felt like a kid in a candy store
Anyway the moral of this story is that its not hard to get away with using a scanner on a plane its about the same as using a video cam on take off and landings (BTW I do that to) ssssssssss please don't tell anyone !! lol
