With a Kindle, there really is no "Off." Only "Sleep" and "A Tad Bit Deeper Sleep with No Screen-Saver." If it were truly off... you'd have to go through a long boot-up procedure (the same one you experience when you do a Restart) when you turned it back "On." Instead, it comes back on in seconds with a flick of the switch. I'm guessing "Sleep with No Screen-Saver" is what the Airlines are looking for in an Off. Even if they're unaware/don't care about the distinction.
