You’ll be grateful for this when you’re crammed in economy class and need to get some work done. The Aero-Tray mounts securely onto your seatback tray with two elastic straps and nonslip rubber feet. It’s adjustable, and the bottom shelf and has a retractable beverage shelf that holds snacks and drinks at a safe distance way from electronics. It also doubles as a protective carrying case and is only $59.
