The D-5 may be covered by Federal Aviation Agency regulations which
prohibit use of certain "portable electronic devices" on airliners, 
since these may possibly interfere with radio navigation instruments.  I 
would check with the airline before using it.  Assuming the unit is properly 
designed I doubt whether there would be a problem, but perhaps it's not.  
The prohibition does include AM and FM radios, since the local oscillator in 
these might interfere with ADF and VHF navaid recption.

I used my D-5 this week on United and Continental.  Neither one said no.

I don't see how people can listen to CDs on airplanes.
The constant roar of engines overpowers any sonic advantage of CDs.
I've found that I can't even listen to good home-recorded
tapes on airplanes if there's a wide dynamic range.
For example, much of Holst's "The Planets" is inaudible on planes
(except, of course, "Mars, the Bringer of War").
On planes, I usually just stick with David Bowie, Talking Heads,
(for classics) Vivaldi's "Four Seasons", and the like.
