Flying with your dog isn’t always as simple as booking a seat and showing up. Between paperwork, carrier restrictions, and hidden fees, it can feel more like navigating a puzzle than a vacation plan.
If you’re planning to bring your pup on a plane—whether in-cabin or cargo—here’s what the airlines may not spell out clearly (but you absolutely need to know).
Cabin vs. Cargo: Know the Difference
In-Cabin Travel
Small dogs (usually under 20 pounds including their carrier) can often fly under the seat in front of you. But…
- Only a limited number of pets are allowed in-cabin per flight—book early!
- Airlines charge a separate pet fee (often $95–$150 each way)
- Carrier size and type must meet specific dimensions (soft-sided is often preferred)
Checked Cargo or Hold
Larger dogs must usually fly as checked baggage or cargo. Airlines have strict rules and only accept pets under safe conditions.
- Breed restrictions apply—many airlines don’t allow brachycephalic (flat-faced) dogs like Bulldogs or Pugs
- Temperature must be within safe range for pet handling at departure and arrival airports
- Airlines may require specific crate types (IATA-compliant)
The Airline Checklist (That’s Not on Their Homepage)
1. Paperwork Requirements Vary by Airline
Most U.S. carriers require a health certificate dated within 10 days of travel. International flights may need vaccination records, USDA endorsement, or quarantine documents.
2. Emotional Support Animal (ESA) Rules Have Changed
As of 2021, most U.S. airlines no longer recognize emotional support animals. Only trained service dogs fly for free under ADA protection.
3. There Are Hidden Costs
- In-cabin pet fee (per segment, not round-trip)
- Crate or carrier fees if purchased at the airport
- Possible layover kennel fees for long flights
4. You May Get Separated During Boarding
If your dog flies cargo, you’ll check them in at a separate facility hours before your own flight. You might not see them again until baggage claim or cargo pickup after landing.
How to Prepare Your Dog for Flying
- Crate train early: Make sure your dog is calm and comfortable in their carrier or crate.
- Exercise before the flight: A long walk helps reduce restlessness.
- Pack a travel bag: Include food, water bowl, leash, ID, calming chews, and vet documents.
- Attach contact info to the crate: Include your phone number and destination address.
Tips for Smooth Airport Navigation
- Arrive early to allow for pet check-in and potty breaks
- Use airport pet relief areas (most U.S. airports have one)
- Keep your pet calm during security (TSA will ask you to carry them through the scanner)
Airline-Specific Pet Policies (Always Double-Check)
- Delta: Allows pets in-cabin and cargo, breed restrictions apply
- United: Only allows in-cabin pets, no longer offers PetSafe cargo service
- Southwest: In-cabin pets only (domestic only), no cargo transport
- Alaska Airlines: Pet travel-friendly, allows in-cabin and cargo under strict conditions
Final Thoughts
Flying with your dog takes more than just good intentions—it takes prep, paperwork, and flexibility. But with the right research, packing, and mindset, it’s completely doable (and worth it for tail-wagging reunions at your destination).
When in doubt, call the airline directly—because no one wants surprises at the gate.
