Mr. Peanut's
A frameless 18 x 11.5 x 11.5-inch carrier that the maker says can flex to 8.5 inches high, with ventilation on five sides, self-locking zippers, warm and cool pad options, and a strap that converts to a leash. The published recommendation is up to 25 lb, but the stated best fit is a pet under roughly 17 inches long while lying down; dimensions and comfortable posture matter more than the generous weight ceiling.


Sturdi
A lightweight carrier with flexible height rods, mesh ventilation, zipper clips, padded interior, washable fleece pad, and several size profiles. Sturdi explicitly excludes XL and XXL from its in-cabin airline-compliant claim. The current listing is a final-sale clearance item, so buyers need to choose a flight-compatible size and verify fit before purchase.


Roverlund
A 3-in-1 carrier, travel bag, and mobile bed with tear-resistant mesh, luggage sleeve, leak-resistant floor, and a shoulder strap that converts to a leash. Small is listed at 16 x 10.5 x 10.5 inches up to 15 lb and Large at 18 x 11.5 x 11.5 inches up to 25 lb; the rear insert can reduce height by about 0.5 inch. The Small selection was unavailable when checked, and neither size is universal for every flight.


Away
A polished 18.7 x 10.8 x 10.75-inch carrier for pets up to 18 lb, with three mesh sides, privacy screen, washable sherpa bedding, trolley sleeve, organized pockets, and car-seat latches. It is CPS certified for car use. Away says it fits under most major-airline seats and meets FAA requirements, but those statements do not override the airline's flight- and aircraft-specific acceptance decision.

Sleepypod
A 16-to-22-inch expandable/compressible carrier for pets up to 18 lb, with four-sided mesh, privacy panel, rigid floor, washable bedding, trolley sleeve, and a design that also serves as a CPS-certified car restraint. Its adaptable length helps with varied under-seat spaces, but its fixed 10.5-inch width and height still have to match the exact airline, aircraft, and seat.

Rabbitgoo
A budget-friendly Y-shaped mesh harness with four adjusters, two side buckles, reflective trim, and a 4.9-foot leash. It offers strong value and broad color choice, but the size ranges have gaps and public reviews confirm that a determined cat may still back out.
