The other thing is that I'd imagine even with highly trained observers posing as passengers seated near him, the chances this would be successful at capturing something would be fairly low. He'd have to enter the passwords while they're watching, and with a reasonably good view of the keyboard and screen, all the while being undetected. This doesn't seem like a sure thing, something you'd only attempt if you REALLY wanted the passwords as part of a very important investigation.
