When working on the flight, be sure not to share your company's confidential information with your neighbours. This is perhaps more of an issue in conventional business class arrangements such as AA or United rather than the head-to-toe format used by BA. Privacy screens can be installed on your laptop screen to ensure thoses sitting next to you can't sneak a peek at your screen. After all, after the nth re-run of movie classics and 'two and a half men' on the entertainment system, your fellow passengers may find your computer more interesting! You can order screens online or you can pick on up at most computer/office supply stores.
