Understand IATA vs. Airline Requirements

IATA 61E is the international standard, but each airline adds its own rules on size, ventilation, and latch style. We checked Delta, United, Southwest, and American requirements and found they all overlap on the basics, but some reject crates based on exact measurements. Always call your airline before buying and ask for their specific kennel requirements, not just the general policy.

Measure Your Dog Properly

Your dog needs to turn around completely and stand without touching the roof. We measured this wrong on our first test and ordered a size too small. Measure your dog's length from nose to rear, then add 4 inches. Measure height from floor to the top of his head when standing normally, then add 2 inches. Use these final numbers to pick a crate size, not your dog's weight.

Check Ventilation Coverage

Plastic crates often have ventilation only on the front and sides, which leaves the back corner stuffy. Impact and Ruff Tough crates ventilate all four sides, which matters if your flight has long tarmac waits. Count the vent holes on all four sides when comparing models. Heat buildup is a real risk, especially in summer or on connecting flights where the crate sits in baggage areas.

Consider Weight and Transportation

A 60-pound aluminum crate is not something you casually move around after your trip ends. If you fly once a year or less, the lighter plastic or composite options make sense. If you travel with your dog regularly, the weight investment in aluminum pays off because you'll actually set it up correctly each time and not resent moving it.

Verify Pre-Flight Acceptance

Don't assume your chosen crate will pass inspection at the airport. We recommend taking a photo of your crate next to a ruler and emailing it to your airline's pet service email before booking. Ask them to confirm in writing that your specific model meets their requirements. This takes 24 hours and saves you from arriving at the airport with a rejected crate.

Frequently Asked Questions

Can I use a soft-sided dog travel crate on an airplane?
No. TSA and IATA require rigid crates with secure latches for cargo holds. Soft-sided crates collapse under pressure and do not provide adequate protection. Only hard plastic, composite, or aluminum crates meet airline safety standards.
What size kennel does my dog need?
Measure your dog standing naturally. Add 4 inches to body length and 2 inches to height. Your dog must turn around completely and stand without touching the roof or walls. Check your airline's specific dimensions because they often restrict larger sizes.
Do I need an airline-approved kennel or just any sturdy crate?
You must use an IATA-approved crate. Your home dog crate will be rejected at airline check-in. Airlines have specific latch, ventilation, and dimension requirements that only airline-certified kennels meet. Do not attempt to use standard home crates for air travel.
How much does shipping cost for a large airline crate?
Airline crates cost $30-80 to ship depending on size and destination. Consider buying from a local pet store if available to avoid heavy shipping fees. Amazon often offers free shipping on large crates, and Chewy sometimes does too if you have a membership.
Can I take a dog kennel as a personal item instead of checked baggage?
No. Kennels are always checked cargo. Your dog travels in the pressurized cargo hold with climate control. Airlines do not permit kennels in the cabin as a personal item, even on small dogs.
Is a plastic or metal kennel better for air travel?
It depends on your dog and climate. Metal conducts heat away faster, which helps in hot weather. Plastic is lighter and easier to move. Composite blends both. For long flights or hot climates, metal or composite is safer. For short flights and frequent travel, plastic is practical.

Bottom Line

Buy the Impact Dog Crate Airline Series if you fly with your dog regularly or want the most durable option. The aluminum frame and full ventilation keep dogs safer and calmer than plastic alternatives, and handlers respect the engineering. If you fly once a year, the Petmate Sky Kennel gives you IATA compliance and airline acceptance for half the price. Either way, verify your specific airline's requirements before ordering.
