Side-by-side specs
Quick answer: Buy the Sky Kennel if you're actually putting your dog on a plane — it ships with the paperwork kit (LIVE ANIMAL stickers, ID stickers, food and water cup, absorbent pad) that airline check-in counters expect. Buy a Vari Kennel if the crate mostly lives in your house or car and only occasionally flies, or if your dog is too big for the Sky Kennel's 70 lb ceiling. They're both Petmate hard-sided plastic kennels built on the same basic idea; the difference is what comes in the box and how large the sizes go.
The confusing part, explained
Petmate makes both lines, and the shells look nearly identical on a product page. That's not an accident — they're cousins. Both are hard plastic top-and-bottom clamshells with a wire door, ventilation slots, and tie-down holes so handlers can zip-tie the door shut.
What separates them:
Finding the right petmate sky kennel vs vari kennel comes down to matching the features to how you will actually use it.
- The Sky Kennel is the travel-first version. Petmate states it meets IATA requirements for live animal transport and most airline cargo specs, and it comes with the travel accessory kit already inside.
- The Vari Kennel is the general-purpose version. It's described as airline-friendly and meeting most airline cargo specifications, but the listed features emphasize the stay-dry moat, the wipe-clean shell, and housebreaking use — home stuff.
Note the Sky Kennel and Vari sizing overlap barely at all — the 36" Sky tops out at 70 lbs, and the 40" Vari starts at 70 lbs. For a lot of dogs, the "which line" question answers itself on weight alone.
Petmate Sky Kennel (36", 50–70 lbs) — the one built for the airport
This is the default recommendation for a medium-to-large dog with a flight booked. Petmate lists it as meeting IATA requirements for live animal transport plus most airline cargo specifications, with 360-degree ventilation and tie-down strap holes. The included kit — two LIVE ANIMAL stickers, a food and water cup, ID stickers, and an absorbent pad — covers most of the small items a cargo counter will ask about, which saves a frantic pre-flight scramble.
Build-wise it's made in the USA from EcoTEC plastic with a minimum of 90% pre-consumer recycled material, with an easy-squeeze latch door with interlocks and a folding top handle. Interior is 32.5" L × 22" W × 26" H, which Petmate pitches for Australian Shepherd–sized dogs.
Petmate Sky Kennel (21", up to 15 lbs) — cats and small dogs flying cargo
Same design, same accessory kit, scaled to an 18.75" L × 13.5" W × 14.5" H interior for pets up to 15 lbs — puppies, kittens, Chihuahua-sized dogs. At $64.99 it's the cheapest way into the Sky line. If you have a cat and an airline that wants a hard-sided IATA crate rather than a soft carrier, this is the size to look at.
Petmate Vari Dog Kennel (40", 70–90 lbs) — the everyday crate that can fly
Where the Sky leans travel, the 40" Vari leans daily life. It has four-sided ventilation, an easy-open sturdy wire door, tamper-proof holes for zip ties, and a stay-dry moat that pulls fluids away from your dog — Petmate specifically calls this out for housebreaking puppies. Interior is 36.2" L × 24.7" W × 28.8" H for 70–90 lb dogs. It's listed as airline-friendly and meeting most airline cargo specs, but it does not come with the Sky's sticker-and-cup kit.
Petmate Ultra Vari Dog Kennel (48", 90–125 lbs) — for genuinely huge dogs
At 48" L × 32" W × 35" H and rated 90–125 lbs, this is where you go when the 40" Vari isn't enough. It adds wire ventilation, a raised interior, covered door posts, and an easy-open latch, plus tamper-proof zip-tie holes. Assembly is tool-free with metal screws and fasteners. Same USA-made EcoTEC plastic with at least 90% pre-consumer recycled content.
SportPet Airline Compliant LARGE 31.5" — the cheap wheeled alternative
Worth knowing about before you commit to Petmate. It's stated as compliant with the 51st Edition of the IATA Live Animal Regulations, and it adds two things neither Petmate line offers: snap-on/snap-off wheels for dragging through a terminal, and a two-piece design that separates for flat storage. It includes two food/water dishes and four LIVE ANIMAL labels. Interior is 28.75" L × 19.75" W × 21.5" H, sized for dogs up to 28" L × 20" H — Border Collie territory — at $78.00.
SportPet Airline Compliant XXX-LARGE 48" — giant breeds plus wheels
The same formula at Great Dane scale: a 44" L × 29" W × 34.5" H interior for pets up to 44" L × 33" H, with wheels, two top carry handles, an accident moat, reinforced metal hardware, and the same IATA 51st Edition compliance claim. At $363.99 it sits just under the Ultra Vari 48", and the wheels plus collapsibility are the real argument for it over the Petmate.
Honest trade-offs
"Airline compliant" is not a guarantee. Petmate says the Sky Kennel meets IATA requirements and most airline cargo specifications — "most" is doing work there. Individual carriers set their own rules on ventilation on all four sides, metal vs. plastic hardware, and door type, and those rules change. Call your specific airline with the model and dimensions before you buy. Nobody at the counter cares what a product page said.
The Vari's accessories aren't included. The Sky's kit is a real convenience, but stickers, a clip-on bowl, and an absorbent pad are individually cheap. Don't overpay for the Sky if a Vari fits your dog better — just buy the bits.
Neither Petmate line has wheels. A loaded 48" crate with a 100 lb dog inside is a genuinely awkward object. Both SportPet models include removable wheels and carry handles; if you're going solo through an airport, that's a bigger deal than brand loyalty.
Size up carefully. These crates are sold by dog weight, but airlines size by the dog standing up: full height, ears or head clearance, and room to turn. Measure your dog and compare to the interior dimensions in the table above, not to the weight range.
Price spread is wide. $64.99 for the small Sky Kennel to $377.95 for the Ultra Vari. If you're flying once, a smaller correctly-sized crate beats an oversized one — and oversized crates get rejected at cargo more often than undersized ones get approved.
FAQ
Is the Sky Kennel just a Vari Kennel with stickers? Not quite. Petmate lists the Sky as meeting IATA requirements for live animal transport with 360-degree ventilation and an easy-squeeze latch with interlocks. The Vari is described as airline-friendly with four-sided ventilation and a stay-dry moat. Different feature emphasis, overlapping purpose.
Which one for a dog over 90 lbs? The Sky line listed here stops at 70 lbs and the standard Vari at 90 lbs, so you're looking at the Petmate Ultra Vari Dog Kennel (48", 90–125 lbs) or the SportPet XXX-LARGE 48". Pick based on whether wheels and collapsible storage matter to you.
Can I use these as an everyday home crate? Yes — the Vari line in particular is described for home and travel, with a wipe-clean shell and a moat that helps with housebreaking. Hard-sided plastic is darker and more den-like than wire, which some dogs prefer and some don't.
Should I read owner reviews before deciding? Absolutely, and read them for your specific size. Latch durability, door alignment, and how a crate holds up to cargo handling are exactly the things long-term owners write about, and they vary by size within a product line. Sort by most recent and filter to your size before you buy.
