The Airline Route: An IATA-Compliant Hard Crate
If flying is a real branch of your plan, the crate has to clear the IATA bar above, and the Petmate Sky Kennel is the one on this comparison built and stated to do it. Petmate’s own product page says the Sky Kennel “compliant with the standards specified in the 51st edition (2025) of the IATA Live Animals Regulation,” with four-way ventilation across the door, sides, and back. The 36-inch size is rated for 50-70 lb dogs, with an interior of 32.5in L x 22in W x 26in H and an empty weight of 20.75 lbs, and the line runs from a 21-inch (up to 15 lbs) to a 48-inch (90-125 lbs).
It ships ready to fly: two “LIVE ANIMAL” stickers, a food-and-water cup, ID stickers, and absorbent bedding, all in the box. Petmate still adds the caveat every honest source repeats, that you should “always recommend contacting your airline before traveling to verify their requirements,” because IATA sets the floor and individual airlines layer their own rules on top.
What it is not is crash-tested. The Sky Kennel isn’t on Center for Pet Safety’s certified directory, and IATA compliance is a cargo-handling standard, not a vehicle-crash rating. It’s also the heavier, bulkier buy: 20.75 lbs empty for the 36-inch, no fold-flat storage, and a plastic wing-nut assembly that’s a slower one-time setup than a snap-together wire crate. That’s the tradeoff you accept for the one thing it uniquely offers, an actual airline path.
The Car Route: A Secured Travel Crate for the Drive-Out
For the drive-out that most evacuations actually are, the job is different: give a large dog room to ride, keep it secured against movement, and store out of the way the other 360 days a year. The folding MidWest iCrate 42in is built for exactly that. Its Amazon listing title describes it as a “42-Inch iCrate for Large Breeds, 71-90 lbs, Double Door Folding Dog Crate with Divider Panel, Leak-Proof Tray & Secure Latches.” That’s the shape of a car crate: roomy, foldable, easy to hose out.
The 42-inch length gives a 71-90 lb dog the room to ride upright and lie down that AVMA calls for, at the lowest price of the two picks here. It folds flat, so it isn’t a permanent footprint in a garage or a packed trunk. And its open wire exchanges more air than a solid plastic shell by design, which is a real comfort factor in the hot months when most hurricane and wildfire evacuations land. (MidWest’s own site describes a tool-free snap-together setup and a “folds flat” claim, but that page returned a server error on our run, so we’re citing the folding and large-breed specs to the manufacturer’s Amazon listing rather than a page we couldn’t load.)
Its limits are the mirror image of the Sky Kennel’s. It has no airline path: an all-wire container fails IATA’s solid-side rule outright. And it isn’t crash-tested. Worse, the one MidWest-brand wire kennel Center for Pet Safety did crash-test failed, which is the next section.
Spec Comparison: Airline Crate vs. Car Crate
|
Petmate Sky Kennel (36in) |
MidWest iCrate (42in wire) |
| Built for |
Air travel (cargo) plus vehicle |
Vehicle drive-out plus home |
| Dog weight range |
50-70 lb (six sizes, cat to 125 lb) |
71-90 lb (large breeds) |
| Folds flat? |
No, permanent footprint |
Yes, collapses for storage |
| Airflow |
Solid sides, four-way vent openings |
Open wire, most airflow by construction |
| IATA-accepted for a flight? |
Yes, 51st edition (2025), per Petmate |
No, all-wire mesh not accepted |
| CPS crash-certified? |
No |
No (a brand wire kennel failed CPS 2015) |
| Empty weight |
20.75 lb (36-inch) |
Not published by MidWest |
| Assembly |
Plastic wing nuts |
Snap-together folding |
Every figure here is cited per-row in the product spec tables above and in the sources list at the bottom of the page. The table makes the split concrete: the Sky Kennel wins the one row a wire crate can never win (a flight), and the iCrate wins storage, airflow, and price for the drive that’s far likelier to happen.
The Crash-Test Gap Neither One Closes
Here’s the fact that matters most and that “airline approved” quietly obscures: neither of these crates is crash-tested, and IATA compliance does nothing to change that.
Center for Pet Safety is the only US nonprofit that runs and publishes independent crash tests for pet crates and carriers. Its certified directory is a short list of double-wall rotomolded crates (the Gunner G1, Cabela’s GunDog, and Lucky Duck Lucky Kennel lines) plus a handful of soft carriers. Neither a standard single-wall airline plastic kennel like the Sky Kennel nor a folding wire crate is on it.
For the wire crate specifically, the evidence is worse than absent. CPS’s 2015 crate study crash-tested a MidWest-brand wire kennel in two anchoring configurations, and both failed. CPS’s conclusion was that “wire crates should be considered as distraction prevention tools and will not provide significant protection in the case of an accident.” That’s not a knock on this exact iCrate SKU (CPS didn’t identify the product line in its published results), but it’s a documented failure mode for the material.
So if a vehicle collision is genuinely your top concern, neither pick on this page is the answer, and the airline crate’s IATA badge doesn’t make it one. That’s a separate, narrower buying decision for the CPS-certified rotomolded crates, and it’s covered in full on our vehicle loading and restraints for multiple pets guide. What you can do with either crate here is follow AVMA’s guidance: secure it against movement and position it toward the center of the vehicle, which is a real improvement over a loose crate even without a crash rating.
Decision Framework by Most Likely Route
| Your most likely route |
Best pick here |
Why |
| Drive-out, large dog, tight storage |
MidWest iCrate 42in |
Folds flat, runs cooler, roomy for the ride, lowest cost |
| Flying is a realistic branch, or a facility requires IATA |
Petmate Sky Kennel 36in |
Only pick built to the current (2025) IATA standard |
| In-cabin flight with a small pet |
Neither; a soft under-seat carrier |
See the airline-carrier roundup for under-seat sizing |
| Vehicle crash protection is the priority |
Neither; a CPS-certified rotomolded crate |
See the car-loading and restraints guide |
| Both drive and fly are genuinely live |
Own both |
One crate can’t optimize both routes |
The Honest “Buy for Your Likeliest Route” Verdict
The temptation is to buy the crate that sounds like it covers the most situations, and “airline approved” sounds like that crate. It usually isn’t. An IATA kennel is optimized for a trip most households will rarely or never take, and it pays for that optimization in weight, bulk, cost, and storage every single day it sits in the garage waiting for a flight that may not come.
Buy for the route you’ll most likely take. For most people that’s a drive, which makes the secured car crate the first purchase and, for a large dog, the folding iCrate the specific pick. Add the IATA Sky Kennel only when flying is a real, planned-for branch, not a hypothetical, or when a shelter or boarding facility hands you an IATA requirement in writing.
And if both routes are genuinely live for your household (you live somewhere a fly-out is plausible and you drive the rest of the time), the honest answer is that one crate can’t do both jobs well, and owning the right crate for each route is a defensible plan rather than a splurge. That’s a real cost. It’s also cheaper than discovering at an airport or a shelter parking lot that the one crate you bought was built for the trip you didn’t take.
For the wire-versus-plastic version of the drive-out crate decision, including the small hard-shell option for a cat, see our wire crate vs. plastic crate for evacuation comparison. For small dogs and cats where a soft-sided bag is realistically on the table, our soft-sided vs. hard-sided carrier guide runs that trade-off the same way.
When It’s the Pet, Not the Crate
A crate contains and transports an animal. It doesn’t diagnose one. If your pet shows heavy panting, drooling, disorientation, vomiting, collapse, or a change in gum color during loading, transport, or heat exposure, that’s a call for a veterinarian, not a gear decision. And never leave a pet crated and unattended in a parked car during evacuation staging, wire or plastic, at any outdoor temperature; a parked vehicle heats fast and no crate slows that down.
