9.0OUT OF 10
Build Quality9.2
Airline Fit9.0
Ease of Use8.8
Owner Verdict9.0
This is the pick for the pet owner who wants a single box solution for their first flight. The Petmate Sky Kennel is IATA compliant, which means it meets the International Air Transport Association requirements that most major airlines follow. It’s made in the USA from heavy duty plastic, and it ships with a “Ready to Fly” kit that includes a live animal sticker, ID tags, and a reusable zip tie set.
The 28-inch interior fits dogs between 15 and 30 pounds, which covers a huge range of small to medium breeds. User reviews average 4.4 out of 5 stars, with owners consistently praising the sturdy construction and the peace of mind that comes from using a brand that’s been making airline kennels for decades.
Flaws but not dealbreakers. The Sky Kennel is a bit heavier than some competitors at that size, and the plastic can feel rigid if you’re used to a soft-sided carrier. Some owners mention that the latch system, while secure, takes a little practice to close quickly at the check-in counter.
If you need a bigger size for a dog closer to 50 pounds, the
Petmate Ultra Vari 32in Medium further down offers a similar build quality with more interior room.
⚠Sizing: Measure your dog from nose to tail base and from paw to top of head while sitting. The kennel must be long enough for your dog to stand, turn around, and lie down. Many owners buy one size up to be safe, but check your airline’s specific dimensional limits first.
Pros
- ✓IATA compliant for most major airlines so you can fly with confidence
- ✓Made in the USA from heavy duty plastic that withstands baggage handling
- ✓Includes ready-to-fly essentials like zip ties, ID tags, and live animal stickers
- ✓Reliable 4.4-star average from thousands of verified buyers
Cons
- ✕Heavier than some plastic kennels at this size, which adds to checked baggage weight
- ✕Latch system takes a bit of practice to close securely under time pressure
- ✕Only fits dogs up to 30 pounds, too small for many medium and large breeds
Best for: Pet owners flying with a small to medium dog who want a complete, ready-to-go kennel that meets airline requirements right out of the box.

Owner Verdict8.9
This is the pick for the owner who wants one kennel for the plane and the living room. The Petmate Vari Dog Kennel is designed as a durable plastic pet carrier that works for both airline travel and everyday home use. It’s available in a 28-inch size that fits the same 15 to 30 pound dog range as the Sky Kennel, but the Vari has a slightly different shape that some owners find more comfortable for long-term crate training.
With a 4.5 out of 5 star average from reviewers, this is the highest rated model in this lineup. Owners consistently mention that the durable plastic holds up well to being knocked around in the cargo hold, and the taupe and black color scheme hides scuffs better than lighter colored kennels.
Flaws but not dealbreakers. The Vari doesn’t come with the same ready-to-fly kit as the Sky Kennel, so you’ll need to buy zip ties and a live animal sticker separately. The wire door feels a bit lighter than the Sky Kennel’s door, though owner reports don’t show any durability failures.
If you want the ready-to-fly extras included, the
Petmate Sky Kennel at the top of this list is the better choice for first-time flyers.
⚠Compatibility: This kennel is airline friendly for most carriers, but always double-check your specific airline’s kennel requirements before you buy. Some budget airlines have slightly different dimensional rules.
Pros
- ✓Highest owner rating in this lineup at 4.5 out of 5 stars
- ✓Durable plastic construction holds up well for both air travel and home crate use
- ✓Airline friendly design meets most major carrier requirements
- ✓Neutral taupe and black color hides scuffs from baggage handling
Cons
- ✕Does not include ready-to-fly accessories like zip ties or live animal stickers
- ✕Wire door feels slightly less substantial than the Sky Kennel’s door
- ✕Only one size available in this model, limiting options for larger dogs

Owner Verdict8.0
This is the pick for the owner of a large breed dog who needs a wheeled solution for airport terminals. The SportPet Airline Compliant X-LARGE measures 32.25 inches in length, which fits dogs up to 32 inches long and 23 inches tall. It comes with removable wheels that make hauling a heavy kennel through the airport much easier, and those wheels pop off for cargo loading.
This model also includes two food bowls and a collapsible design that makes storage easier when you’re not traveling. The cream and gray color scheme is distinctive, and the plastic shell is durable enough for the cargo hold. With a 4.6 out of 5 star average, owners particularly appreciate the wheel set for larger dogs that push the kennel weight close to 20 pounds empty.
Flaws but not dealbreakers. The removable wheels are a great feature, but some owners report that the wheel attachment points can feel a bit wobbly when navigating rough terminal floors. The plastic also feels slightly thinner than the Petmate Ultra Vari models, though it has held up well in owner reviews.
If you need a heavier duty plastic for a very strong dog, the
Petmate Ultra Vari 40in below uses a thicker wall construction that might stand up better to an anxious chewer.
⚠Wheels: Always remove the wheels before checking the kennel at the gate. Most airlines require the kennel to sit flat on the cargo floor without wheel attachments. Keep the wheels in your carry-on for easy terminal transport.
Pros
- ✓Removable wheels make airport terminal transport much easier for large kennels
- ✓32.25-inch interior fits large breed dogs up to 32 inches long
- ✓Includes two food bowls and a collapsible design for storage
- ✓Highest rating in the lineup at 4.6 out of 5 stars
Cons
- ✕Wheel attachment points can feel wobbly on uneven terminal floors
- ✕Plastic shell feels slightly thinner than Petmate Ultra Vari models
- ✕Heavier empty weight means higher baggage fees for some airlines

Ease of Use7.5
Owner Verdict8.2
This is the pick for the owner of a heavy large breed dog who needs a max-size airline kennel. The Petmate Ultra Vari 40in is built for dogs weighing 70 to 90 pounds, making it one of the largest airline-compatible kennels available. It’s made in the USA from heavy duty plastic that’s noticeably thicker than the SportPet model, which matters when you have a strong dog who might push against the walls during travel.
At 40 inches inside, this kennel fits Labrador Retrievers, Golden Retrievers, German Shepherds, and similar sized breeds. The Ultra Vari uses a wire door with a secure latch system, and the top and bottom halves bolt together with the included hardware. Owner reviews average 4.3 out of 5 stars, with most praise going to the tank-like construction.
Flaws but not dealbreakers. This is a heavy kennel, even by airline standards. The empty weight is significant, and you’ll want to check your airline’s maximum weight limit for checked pets. Some owners also note that the 40-inch size can be too large for certain airline cargo holds, so always verify with your carrier before booking.
If you need a wheeled option for a large dog, the
SportPet 32.25-inch X-LARGE above is lighter and easier to maneuver through the airport.
⚠Sizing: The 40-inch kennel is very large. Before you buy, measure your dog’s length from nose to tail base and add 2 inches minimum. Also measure your dog’s height from paw to top of head while standing. The kennel must meet both dimensions.
Pros
- ✓Heavy duty plastic construction is thicker and more durable than budget models
- ✓Fits large breed dogs from 70 to 90 pounds with 40-inch interior length
- ✓Made in the USA with quality materials and solid hardware
- ✓Secure wire door and bolt-together design for cargo hold safety
Cons
- ✕Very heavy empty weight, which can push baggage fees higher
- ✕No wheels included, so moving it through the airport requires a cart or dolly
- ✕40-inch size may be too large for some airline cargo hold dimensions

Ease of Use7.8
Owner Verdict7.3
This is the pick for the budget-conscious owner of a cat or very small dog who flies infrequently. The Elevon Plastic Kennel is a newer, more affordable option that’s designed to be airline approved for longer travel. It’s a medium-sized kennel that works best for small breeds and cats, and it’s noticeably lighter than the Petmate equivalents, which helps keep baggage fees down.
With a 4.1 out of 5 star average, early buyers generally report that it does the job for the price. The plastic construction is adequate for occasional use, and the kennel includes ventilation slots on all sides for airflow. It’s a simple, no-frills solution for the traveler who doesn’t want to spend a lot on a kennel that might only get used once or twice a year.
Flaws but not dealbreakers. The plastic is definitely thinner than the Petmate models, and some owners note that the latches feel less robust. If you have a dog who is prone to anxiety or chewing, the lighter construction might not hold up as well. The kennel also has fewer overall reviews than the more established Petmate lineup.
If you need a more durable kennel for a small dog that travels frequently, the
Petmate Sky Kennel at the top of this list is a better long-term investment with thicker plastic and a proven track record.
⚠Compatibility: This is a newer model with fewer long-term owner reviews. If you’re planning a single flight and want to save money, it’s a reasonable choice. For frequent flyers, the extra cost of a Petmate model buys proven durability.
Pros
- ✓Budget-friendly price point for owners who fly infrequently
- ✓Lightweight design helps keep checked baggage weight lower
- ✓Airline approved for longer travel with small dogs and cats
- ✓Ventilation slots on all sides for good airflow during travel
Cons
- ✕Plastic shell is thinner than Petmate models, less durable over time
- ✕Latches feel less robust and may not hold up to anxious dogs
- ✕Fewer owner reviews and less long-term track record than established brands

This is the pick for the owner of a medium-sized dog like a Beagle, Cocker Spaniel, or small Border Collie. The Petmate Ultra Vari 32-inch Medium is built for dogs weighing 30 to 50 pounds, and it’s one of the most proven models in this lineup with a 4.5 out of 5 star average from thousands of reviews. It’s the same heavy duty plastic construction as the 40-inch version, just in a more manageable size for smaller dogs.
This kennel is made in the USA and uses the same bolt-together design as the larger Ultra Vari. The 32-inch length gives most medium dogs enough room to stand, turn around, and lie down comfortably. Owners consistently praise the durability and the fact that it doubles as a sturdy home crate between trips.
Flaws but not dealbreakers. Like the 40-inch version, this kennel is heavy for its size. The 32-inch model weighs about 18 pounds empty, which adds to your checked baggage total. Some owners also note that the wire door could use a more secure latch, though no widespread failure reports exist.
If you need a lighter option for a 30-pound dog, the
Petmate Sky Kennel 28-inch is 5 pounds lighter and still fits dogs up to 30 pounds comfortably.
⚠Sizing: The 32-inch size is for dogs up to 50 pounds. If your dog is closer to 55 or 60 pounds, consider the 40-inch Ultra Vari instead. An overcrowded kennel can cause stress and breathing issues during flight.
Pros
- ✓Highly rated at 4.5 out of 5 stars from thousands of verified buyers
- ✓Heavy duty plastic construction made in the USA for long-lasting durability
- ✓Fits medium dogs from 30 to 50 pounds with a 32-inch interior length
- ✓Works well as both a travel kennel and a home crate for daily use
Cons
- ✕Heavy empty weight of 18 pounds adds to checked baggage fees
- ✕Wire door latch could feel more secure, though no failure reports
- ✕No wheels or travel accessories included in the box

This is the pick for the owner who wants a kennel that works for both indoor and outdoor use, with airline approval as a bonus. The Pet Crate Durable Heavy Duty Dog kennel is available in 7 different sizes, making it one of the most size-flexible options in this lineup. It’s designed as a “Pet Palace” style kennel that can be used in the backyard, on the patio, or as a travel crate.
The heavy duty plastic construction is solid, and the airline-approved design means it meets the requirements for most carriers. With a 4.0 out of 5 star average, owners generally appreciate the value for the money, especially considering the size range available. The kennel comes with a secure door latch and ventilation on multiple sides.
Flaws but not dealbreakers. The build quality is good but not as premium as the Petmate Ultra Vari line. Some owners note that the plastic can feel a bit more flexible, especially in the larger sizes. The 4.0 star average is the lowest in this lineup, with some owners reporting issues with the latch alignment over time.
If you need a more durable option for a large dog that travels frequently, the
Petmate Ultra Vari 40in offers thicker plastic and a stronger overall build.
⚠Sizing: With 7 sizes available, measure your dog carefully and check the specific dimensions for the size you choose. The “Large” size for this brand may differ from other brands, so always verify interior length.

Buying Guide: What to Know Before You Buy an Airline-Approved Dog Kennel
Choosing the right kennel for air travel comes down to three main factors: sizing, airline compliance, and build quality. Here's what matters most.
How Do You Measure Your Dog for an Airline Kennel?
The single most important rule is that your dog must be able to stand, turn around, and lie down comfortably inside the kennel. Airlines measure this in specific ways. You need to measure your dog's length from the tip of the nose to the base of the tail, then add 2 to 4 inches.
That's the minimum interior length you need.
You also need to measure your dog's height from the top of the head or the highest point of the ears while standing, then add 2 to 3 inches. That's the minimum interior height. Many owners in verified buyer reviews report that they bought one size up from what they thought they needed, and they were glad they did.
What Does IATA Compliance Mean for Your Kennel?
The International Air Transport Association (IATA) sets the standards that most airlines follow for live animal transport. An IATA compliant kennel like the Petmate Sky Kennel has specific features: rigid plastic construction, a secure door latch, ventilation on at least three sides, and a leak-proof floor. Some kennels in this list are "airline friendly" or "airline compliant" but may not be fully IATA certified.
Always check with your airline before booking.
What Build Quality Should You Expect at Different Price Points?
The kennels in this lineup range from budget-friendly options like the Elevon to heavy duty models like the Petmate Ultra Vari. The price difference isn't just about brand. It's about plastic thickness, latch quality, and overall durability.
The Petmate Ultra Vari 32in Medium uses thicker plastic than the Elevon, and it shows in the owner reviews. The SportPet X-LARGE sits in the middle with a good balance of features and cost.
Who Should NOT Buy Best Airline-Approved Dog Kennel
An airline-approved hard-sided kennel is the wrong purchase for three kinds of buyers. Here's who they are, and what to look at instead.
You Need a Kennel for a Dog Over 100 Pounds
Most airline cargo holds have a maximum kennel size limit, and the 40-inch kennels in this list top out at around 90 pounds. If your dog weighs more than that, you need to look at custom kennel options or check with your airline about their specific large breed policies. Some airlines have weight restrictions that simply don't allow dogs over a certain size in the cargo hold.
You Want a Soft-Sided Carrier for Under the Seat Travel
If your dog is small enough to ride in the cabin with you, you don't need a hard-sided airline kennel. Soft-sided carriers that fit under the seat are lighter, easier to carry, and more comfortable for your dog to travel in the cabin. Look for carriers that are specifically designed for under-seat use and check your airline's dimensions for carry-on pet carriers.
You Need a Daily Crate That's Also a Travel Kennel
If you want a single crate for both daily use and air travel, the hard-sided kennels in this list work well. But if you need a crate that's lighter and easier to move around the house every day, a wire crate might be a better choice. You can use a wire crate at home and buy a separate airline kennel for travel.
Many owners find this two-crate approach works better than trying to use one kennel for everything.
Final Verdict
The Petmate Sky Kennel Air Travel is the best choice for most pet owners. It's IATA compliant, made in the USA, and includes the ready-to-fly essentials you need. If you're flying with a small to medium dog, this is the kennel that gives you the least hassle.
Want a kennel that works for both home and travel? The Petmate Vari Dog Kennel has the highest owner rating in this lineup and works well as a daily crate. Need a wheeled option for a large breed?
The SportPet X-LARGE 32.25-inch makes airport terminals much easier to navigate.
If you have a dog over 90 pounds or you want a soft-sided carrier for cabin travel, check the "Who Should NOT Buy" section above before you spend anything. The right kennel makes flying with your dog safer and less stressful for both of you.
FAQ
What's the best airline-approved dog kennel overall?
The Petmate Sky Kennel Air Travel is the best overall pick. It's IATA compliant, made in the USA, and comes with a ready-to-fly kit that includes zip ties, ID tags, and live animal stickers. It fits dogs 15 to 30 pounds and has a 4.4 out of 5 star rating from verified buyers.
How do I know if my dog's kennel will fit on my airline?
Always check your specific airline's dimensional requirements before you buy. Most airlines follow IATA guidelines, but some budget carriers have different rules. Measure your kennel's exterior dimensions and compare them to your airline's published limits for checked pets.
Can I use a soft-sided carrier for my dog on a plane?
Yes, if your dog is small enough to ride in the cabin with you. Soft-sided carriers that fit under the seat are allowed by most airlines for small dogs and cats. The weight limit is usually around 15 to 20 pounds, including the carrier.
Check your airline's specific policy.
What's the difference between the Petmate Sky Kennel and the Petmate Vari Kennel?
The Sky Kennel comes with a ready-to-fly kit that includes zip ties, ID tags, and live animal stickers. The Vari Kennel is a simpler design that works well for both home and travel use. Both are IATA compliant and made in the USA.
The Sky Kennel has a slightly more robust latch system, while the Vari has a 4.5 star rating from owners.
Should I buy a kennel one size up for my dog?
Many owners recommend buying one size up from the minimum, as long as it still fits your airline's dimensional limits. Your dog needs room to stand, turn around, and lie down comfortably. An overcrowded kennel can cause stress and breathing issues.
Just verify that the larger size stays within your airline's limits.
