The Sky Kennel is what veterinarians and breeders recommend when a cat must fly cargo. It is not glamorous, it is not lightweight, and it is the carrier I would put my own cat in for a transatlantic flight. After four months of car use and two cargo flights, our Medium unit shows no cracks, the door still latches firmly, and all six locking points hold tight.
Why you should trust this review
I have flown with cats four times in the last three years across two carriers and one airline transfer. We bought the Sky Kennel Medium at retail from PetSmart and used it as our primary travel crate from November through April. I confirmed compliance with United and Delta cargo desks before each flight, photographed the locking hardware before and after each trip, and timed the load-and-secure cycle. See the broader testing notes on methodology.
How we tested the Sky Kennel
- Two cargo flights LAX-LHR and JFK-LAX with our 11-lb domestic shorthair
- Sixteen car trips of 30+ minutes for vet, daycare, and weekend travel
- Hardware inspection after each flight, all six locking points held without loosening
- Verified ventilation against IATA LAR by measuring the open area on all four sides
- Compared to a Sherpa Original Deluxe Medium for in-cabin alternative
Who should buy the Sky Kennel?
Buy it if your cat must fly cargo, if you drive long distances, or if you live in a hurricane or wildfire zone where you may need to evacuate fast. Skip it for in-cabin flights, the Sky Kennel does not fit under most airline seats. Skip it for daily vet visits unless you have a 25-lb cat, the Medium is overkill for routine use.
Airline compliance: where most carriers fail
The Sky Kennel is IATA Live Animal Regulations compliant when correctly assembled, which is why airlines accept it. The mistake travelers make is using the plastic snap latches that ship out of the box. Airlines require metal screw bolts at all four corners, the screws are usually included in a small bag taped to the door. Replace the snaps before the flight, tighten to firm-but-not-stripped, and confirm with the cargo desk 48 hours before departure. We had zero issues at LAX, JFK, or LHR with this setup.
Hardware quality after two flights
The squeeze-latch door, two side wing nuts, and four corner bolts all survived two transcontinental cargo flights and 16 car trips without loosening. Visible inspection at four months shows no metal fatigue, no cracking around the bolt holes, and a door that still latches with the same firm click as week one. Compare this to a $49 generic crate I tested last year that had a hairline crack at the corner bolt after one flight.
Ventilation: exceeds airline minimums
IATA LAR requires ventilation on at least three sides for international travel. The Sky Kennel has it on all four. We measured roughly 18 percent open area on the door side and 14 percent on each of the other three sides, which exceeds airline minimums by a comfortable margin and matters for international transit through warm-climate hubs.
Loading: top-off helps with shy cats
Most hard carriers force cats in through the front door, which terrified our cat the first three uses. The Sky Kennel’s top half lifts off entirely once you remove the four corner bolts, which lets you lower a reluctant cat in from above. We use this method for every load now, the cat barely notices.
Cons worth flagging
The Medium is too large for in-cabin flights, get the Sherpa or Sleepypod for cabin travel. Empty weight is 12 lb, which is heavy if you have to walk far through an airport. And the bottom-shell assembly screws are easy to overtighten on first build, snug them by hand, never with a power driver.

Should you buy the Petmate Sky Kennel?
If your cat must fly cargo, the Sky Kennel is the safest mainstream option. It is IATA Live Animal Regulations compliant, accepted by United, Delta, American, Lufthansa, and most other carriers, and the locking hardware survived two transcontinental flights without loosening. It is too large for most under-seat cabin needs, get the Sherpa Original for that. Buy this for cargo, vet transport, or evacuation.
Frequently asked questions
Is the Sky Kennel IATA compliant in 2026?+
Yes when correctly assembled with all six locking points engaged. You must use metal screw bolts (often included, sometimes sold separately) instead of plastic snap latches for cargo. Confirm with your airline 48 hours before departure.
Sky Kennel vs Sleepypod Air: which should I buy?+
Sky Kennel for cargo or vehicle transport. Sleepypod Air for in-cabin flights. They solve different problems. Sky Kennel is hard-sided, oversized for cabin use, and the Sleepypod is soft and fits under all major airline seats.
Which size for an 11-lb domestic shorthair?+
Medium (28x20.5x21.5 in). Cats need to stand up, turn around, and lie down per IATA rules. The Small is too tight for an 11-lb cat. The Intermediate adds height that most cats do not need.
What is the most common assembly mistake?+
Forgetting the metal screw bolts. The kennel ships with 4 plastic snap latches that look secure but airlines reject them. Replace with the included or aftermarket metal screws and tighten to firm but not stripped.
