With the increase in pet-friendly airlines and policies, air travel with pets in 2025 is more feasible and safe than ever but only if you have the right pet carrier.

In this guide, we’ll break down everything you need to know about choosing the best pet carrier for air travel, including top models for 2025, airline regulations, key features to consider.

Why the Right Pet Carrier Matters

Choosing the right carrier for your cat or dog isn’t just about comfort—it’s about safety, compliance, and peace of mind.

A good pet carrier should:

• Offer comfort for the pet
• Be easy for the owner to handle

Failing to choose the correct carrier could result in denied boarding or a very stressful journey for your pet.

Most airlines follow International Air Transport Association (IATA) and TSA guidelines. While details vary by airline, typical in-cabin pet carrier requirements include:

• Soft-sided carriers only
• Must fit under the seat (approx. 18″ L x 11″ W x 11″ H)
• Secure zippers
• Leak-proof base
• Proper ventilation (mesh panels on at least 2 sides)

Factors to Consider When Buying a Pet Carrier

1. Airline Compatibility

Double-check the dimensions and requirements for your airline and specific aircraft model. Some carriers that work for Delta might not for Southwest or JetBlue.

2. Pet Size and Weight

Always measure and weigh your pet before buying. A tight carrier leads to stress and possibly health issues during travel.

3. Ventilation

Look for mesh windows on multiple sides. Good airflow is crucial for temperature regulation.

4. Entry Points

Top and side entries offer flexibility for loading your pet calmly.

5. Material & Construction

Soft-sided carriers for cabin travel; hard-sided for cargo or large dogs. Ensure zippers are lockable and escape-proof.

6. Comfort Features

Removable fleece or memory foam liners can make long flights bearable. Check for leak-proof bottoms.

7. Portability

Carrying straps, backpack options, or rolling carriers help you navigate airports without strain.

Preparing Your Pet for Air Travel

A great carrier is only part of the puzzle. Help your pet adjust:

• Carrier training: Introduce the carrier weeks before the flight
• Practice runs: Let your pet sit in the carrier at home or during short car rides
• No feeding 4–6 hours before flight to prevent nausea
• Use calming sprays or pheromones if your vet recommends it

Tips for a Smooth Flight

• Arrive early: Many airlines have pet check-in steps.
• Line your carrier: Use pee pads or a small towel in case of accidents.
• Carry essentials: Treats, collapsible bowls, a leash, and wipes.
• Stay calm: Pets often mirror your emotions.

FAQs

What size pet carrier fits under an airplane seat?

Most airlines accept carriers no larger than 18″L x 11″W x 11″H, but it varies. Always check your airline’s pet policy.

Can I bring two pets in one carrier?

Generally, no. Most airlines only allow one pet per carrier unless they are young littermates or small enough to fit comfortably with space to move.

Are rolling carriers allowed in-cabin?

Yes, as long as they fit under the seat and are soft-sided. Wheels may need to be removed or tucked away.

Can I use a backpack-style carrier?

Yes, provided it meets the size and ventilation requirements and fits under the seat. Not all backpack carriers are airline-approved.

What if my pet is too large for in-cabin travel?

Pets that exceed in-cabin size limits must travel as checked baggage or cargo in an IATA-approved hard-sided crate. Some airlines restrict cargo travel in extreme temperatures.

Do I need a health certificate for air travel with my pet?

Yes, most airlines and international destinations require a current health certificate from your vet issued within 10 days of travel.

Can I sedate my pet before flying?

No, most airlines and vets strongly advise against sedation, as it can impair breathing at high altitudes. Instead, consider calming pheromone sprays or natural supplements (under vet guidance).

How early should I arrive at the airport with my pet?

Arrive at least 2–3 hours before departure, especially for international flights, to complete pet check-in procedures.

Are pet carriers considered a carry-on item?

Yes, your pet carrier usually counts as your one carry-on item, though some airlines allow a personal item in addition.
