🔎 Tips to Save on Pet Fees

Paying less for pet travel is possible with strategic planning:

1. Book Early

Most airlines limit the number of pets allowed onboard per flight. Booking ASAP increases the chance you secure the lower in-cabin rate instead of cargo.

2. Choose Off-Peak Flights

Flights in mild weather are often prioritized for pets. Avoid hot summer midday flights where airlines may restrict pet onboard due to heat.

3. Consider Cost vs. Convenience

Sometimes a slightly higher pet fee is worthwhile if it reduces stress for your pet or minimizes layovers.

4. Preflight Health Check

Documented health certificates can speed up processing and avoid last-minute fees.

5. Contact Support if Confused

When you’re unsure about booking or have questions about fees, reach out to a flight help center or the airline’s official pet travel help.

For live assistance, you can reach our dedicated help-center at 1 (866) 558-3017. Our specialists can walk you through pet policies, fare differences, and booking logistics from start to finish.

Q1: Which airline really has the cheapest pet fees?

The consistent answer for affordable in-cabin pricing is Southwest, typically at ~$95 each way — making it a top choice for pet parents asking Which Airline Has the Cheapest Pet Fees.

However, fees are only one part of the equation — route flexibility, pet size, and carrier policies also matter.

Usually not. Most airlines charge pet fees per ticketed booking. If you cancel or change flights, pet fees may apply again or be non-refundable unless stated otherwise.

Q3: Can my pet travel internationally in cabin?

International policies vary widely. Many countries require quarantine or additional documentation. Always confirm with the airline and destination country. For support, call our flight help center at 1 (866) 558-3017.

Extras may include:

📍 International shipping paperwork
📍 Special kennels that meet airline standards
📍 Layover holding fees

These can add $100-plus, so plan ahead.

Q5: Can large dogs travel in cabin?

Typically no. Most airlines limit in-cabin pets to a combined pet + carrier weight (usually around 20 lbs). Bigger pets travel as cargo, which affects cost and preparation.
