Best suited for: In-cabin airplane carrier (Small size only)
Also works for: Travel bed
Overall rating: ★★★★★
This is a rolling carrier that can be collapsed (when not in use) to 3.5″ wide. It comes in three sizes: Small (13Hx17Lx9W), Medium (13Hx20Lx9W), and Large (15Hx22Lx11W). It has large ventilation panels on three sides (the fourth side has a large storage pocket), each with privacy panels. It’s very maneuverable, and it’s strong enough that you can stack your other luggage on top if need be. With the ventilation and privacy panels rolled up on the open long side, this carrier would also work as a small, cozy travel bed at your destination.
Only the Small size will work as an in-cabin airplane carrier — all of the edges are rigid, so there’s no fudging with this one. I can’t think of a reason that I’d want the collapsibility feature of this carrier, but maybe you can.
