How to Fly With a Dog: The Complete 2026 Airline and Prep Guide

Flying with a dog takes planning, but it is very doable. Airlines set their own rules, so the details matter. Always confirm current policies with your airline before you book, because fees and requirements change.

Step 1: Decide whether flying is right for your dog

Some dogs handle travel well, and others find it very stressful. Consider your dog's age, health, temperament and breed. Flat-faced breeds, very young or elderly dogs and dogs with heart or breathing problems may face higher risks, and some airlines restrict certain breeds. Talk to your vet before you book.

Step 2: Understand your options

In the cabin: small dogs in an approved carrier that fits under the seat in front of you. Baggage allowances vary; check whether the carrier changes your normal carry-on allowance
Checked baggage or cargo: options for larger dogs vary widely, and many airlines limit or do not offer them. Check each airline's current rules, including temperature restrictions
Service animals: follow separate rules and documentation requirements

Step 3: Read the airline's pet policy

Look for:

Fees, which are often charged each way
Carrier size and type (soft-sided or hard-sided)
Weight limits, which often include the carrier
Number of pets allowed per flight, which is limited, so book early
Age minimums and breed restrictions
Cabin and seat restrictions
Rules for connections and international flights

Step 4: Get the documents

Health certificate. Many airlines and destinations require one, often issued within about 10 days of travel
Rabies certificate and vaccination records
Microchip details
International travel: destination-specific certificates and sometimes government endorsement, with long lead times

Keep digital copies in your digital pet health vault and carry the originals. To book the health certificate exam, find a vet near me.

Step 5: Prepare the carrier and your dog

Choose a carrier that meets your airline's current requirements where your dog can stand, turn and lie down
Leave it out at home for weeks so your dog sees it as safe
Add a familiar blanket and a flat absorbent pad
Practice short trips in the carrier
Make sure your dog wears ID and is microchipped

Step 6: Plan the day of travel

Exercise your dog before you leave
Offer water, and ask your vet about timing of the last meal
Arrive early, since pet check-in can take longer
At security, you will usually take your dog out of the carrier and carry them through while the carrier goes through the scanner. Keep a leash on
Take a collapsible bowl and waste bags

During the flight

Keep your dog in the carrier, under the seat. Speak quietly, and do not open the carrier. Do not rely on sedatives. Many vets advise against sedating pets for flights, because of risks to breathing and circulation, so talk to your vet about options.

After landing

Find a relief area, offer water and give your dog time to settle. Keep the first hours calm.
