At first glance, I thought this carrier was waaaay to big to fit as any airplane carryon, but I was wrong! This Jet Setter ($170 and up) rolls upright and, when laid on the side, slides right under the seat in front of you. Meant for pets up to 15 pounds, this bag weighs only about three pounds with the wheels removed. It comes in a rainbow of colors (I like the camo and titanium best), materials like rugged canvas and ballistic nylon, and offers lots of ventilation for your lil guy – there's even enough pockets to serve as your personal item, too. What's more is that it easily straps into a seatbelt for a safe trip to the airport for your high-flying pets. . . it's time for takeoff!
