Airline-Approved Carrier vs. Car Crate for Pet Evacuation

In our judgment, a secured car crate is the right first buy for most households, because driving is the likelier route. Buy an IATA-compliant airline crate only if flying with your pet is a realistic branch of your plan, or a shelter, boarding facility or breeder requires one. The two crates solve different trips, and one crate rarely does both well. Neither has a Center for Pet Safety (CPS) crash certification.

For a large dog on a drive-out, the folding MidWest iCrate 42in is sized for large breeds, costs less and stores flat. If flying is on the table, the Petmate Sky Kennel 36in is the one whose maker says it is compliant with the 51st (2025) edition of IATA’s Live Animals Regulation. It is heavier and bulkier to store.

Neither is a cabin carrier. A small pet flying under the seat needs a soft under-seat bag, covered in our airline-approved pet carriers roundup. We do not test products; see our review methodology.

Start with the route, not the crate

Decide how you would leave first, because the mode of travel decides most of the rest.

• Drive-out (likelier, in our judgment). You load the pet into your own vehicle and drive to a destination you arranged ahead of time. AVMA’s vehicle guidance says the crate should be “big enough to allow your pet to stand up, turn around, and lie down comfortably”, placed “as near to the center of the vehicle as possible” and secured “to prevent movement.” Nothing about this trip requires airline compliance. It requires enough room and secure placement.
• Fly-out (the less common branch that changes the gear). A road is closed, the hazard is regional, or your safe destination is far enough that flying is the realistic option. For a dog in the cargo hold, the crate now has to satisfy an airline, which means an IATA-compliant kennel.
• Shelter or extended stay. The destination matters more than the crate. The ASPCA says not all shelters accept pets, so you need to decide where your pets will go ahead of time. AVMA’s disaster guidance tells owners to locate and pre-arrange an evacuation site outside the impacted area. A crate does not fix a shelter that will not take pets; a pre-arranged pet-friendly destination does.

That is the case for buying the car crate first and treating the airline crate as the second, rarer purchase.

What IATA compliance requires

Pettravel.com summarizes IATA’s container rules as a specific list. The crate must be a closed container made of fiberglass, metal, rigid plastic, solid wood or plywood. Its sides must be solid, with ventilation openings over the upper two-thirds. Those openings can be up to 1 inch for a dog or 3/4 inch for a cat, spaced 4 inches center to center. Welded metal mesh in a door must have nose-and-paw-proof openings. Door hinges and locking pins must seat a set distance above and below the door opening. Most airlines require metal hardware, and the pet must be able to stand up and turn around comfortably.

A folding all-wire crate has no solid sides, so it does not meet the solid-sides rule and is not accepted for air transport.

Two things follow. First, IATA compliance matters only if a flight is realistic. If you will drive, the solid-side and hardware rules are spec you pay for and carry without using. Second, IATA compliance is a shipping-and-handling standard, not a safety rating for your car. It tells you an airline will accept the crate. It says nothing about a collision on the way to the airport.

The airline route: an IATA-compliant hard crate

If flying is a real branch of your plan, the Petmate Sky Kennel is the crate on this page whose maker states IATA compliance. Petmate’s product page says it is compliant with the 51st edition (2025) of IATA’s 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. The line runs from a 21-inch crate (up to 15 lbs) to a 48-inch crate (90-125 lbs).

It ships with two LIVE ANIMAL stickers, a food-and-water cup, ID stickers and absorbent bedding. Petmate still recommends contacting your airline before traveling to verify its requirements, because individual airlines can add their own rules.

It has no CPS crash certification. The Sky Kennel is not on Center for Pet Safety’s certified directory, and IATA compliance is a cargo-handling standard, not a vehicle-crash rating. It is also the heavier, bulkier buy: 20.75 lbs empty for the 36-inch, no fold-flat storage and a plastic wing-nut assembly that is likely slower to set up than a fold-flat wire crate (our judgment). That is the trade for the one thing it uniquely offers, an airline path.

The car route: a secured travel crate for the drive-out

For a drive-out, the job is to give a large dog room to ride, keep the crate secured against movement, and store it out of the way the rest of the year. The folding MidWest iCrate 42in is the pick here for that. Its Amazon listing title describes a 42-inch double-door folding crate for large breeds, 71-90 lbs, with a divider panel, leak-proof tray and secure latches.

Check that your dog can stand up, turn around and lie down in it, as AVMA calls for. It folds flat, so it does not take up permanent floor space.

Its limits mirror the Sky Kennel’s. It has no airline path, because an all-wire crate has no solid sides. And it has no CPS crash certification; the MidWest wire kennel Center for Pet Safety crash-tested in 2015 failed both anchoring setups, as the next section explains.

Spec comparison

	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, 15 lb to 125 lb)	71-90 lb (large breeds)
Folds flat?	No	Yes, collapses for storage
Airflow	Solid sides, four-way vent openings	Open wire, more airflow by construction
Stated IATA-compliant?	Yes, 51st edition (2025), per Petmate; confirm with your airline	No, all-wire mesh has no solid sides
CPS crash-certified?	No	No (a MidWest wire kennel failed CPS’s 2015 study)
Empty weight	20.75 lb (36-inch)	Not on the listing title

The Sky Kennel wins the one row a wire crate can never win, a flight. The iCrate wins storage, airflow and price for the drive that is far likelier to happen.

The crash-test gap neither crate closes

Neither crate has a CPS crash certification, and IATA compliance does nothing to change that.

Center for Pet Safety publishes independent crash tests for pet crates and carriers. Its certified directory lists crates such as the Gunner G1, Cabela’s GunDog and Lucky Duck Lucky Kennel lines, plus carriers. Neither a standard single-wall airline plastic kennel like the Sky Kennel nor a folding wire crate is on it.

For wire crates the record is worse than absent. CPS’s 2015 crate study included investigative crash tests of a MidWest wire kennel in two setups: anchored with popular rubber straps, and anchored with a strap reinforcement system CPS designed. CPS reported the crate severely deformed in the first test, and the crate failing with the dog striking the seatback in the second. It concluded that “wire crates should be considered as distraction prevention tools and will not provide significant protection in the case of an accident.” CPS did not identify the product line in its published results, so this is not a finding about the exact iCrate. It is a documented failure for a MidWest wire kennel.

If a vehicle collision is your top concern, neither pick here is the answer. That is a separate decision about CPS-certified crates, covered in our vehicle loading and restraints for multiple pets guide. If you are weighing a Gunner against a Ruffland kennel, our Gunner vs. Ruffland kennel comparison sets them side by side on crash certification and weight. With either crate here, follow AVMA’s guidance: secure it against movement and place it toward the center of the vehicle. That beats a loose crate even without a crash rating.

Decision guide by most likely route

Your most likely route	Best pick here	Why
Drive-out, large dog, tight storage	MidWest iCrate 42in	Folds flat, more airflow, room for the ride, lowest price tier
Flying is a realistic branch, or a facility requires IATA	Petmate Sky Kennel 36in	Only pick whose maker states IATA compliance (51st edition, 2025)
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 crate	See the car-loading and restraints guide
Both drive and fly are genuinely live	Own both	One crate cannot serve both routes

“Airline approved” sounds like the crate that covers the most situations. It usually is not. An IATA kennel is built for a trip that, in our judgment, most households rarely or never take, and it costs you weight, bulk, money and storage every day it waits in the garage. Add the Sky Kennel when flying is a planned-for branch, or when a shelter or boarding facility gives you an IATA requirement in writing. If both routes are live, own the right crate for each. That is a real cost, and it is cheaper than finding out at an airport or a shelter parking lot that the one crate you bought was built for the trip you did not take.

When it is the pet, not the crate

A crate contains and transports an animal. It does not 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 is a call for a veterinarian, not a gear decision. 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.
