Flying with your dog is possible — but only if you follow airline rules carefully. Each airline has strict policies around carrier size, dog weight, documentation, and cabin placement, and failing to meet them can result in denied boarding.
This 2026 guide explains the most common airline rules for traveling with dogs, what to expect at the airport, and how to choose the right carrier so your trip goes smoothly.
✈️ Can Dogs Fly in the Cabin?
Yes — small dogs are allowed to fly in the cabin on most airlines if they meet these requirements:
- Dog must fit completely inside an airline-approved carrier
- Carrier must fit under the seat in front of you
- Dog must remain inside the carrier for the entire flight
- Combined weight of dog + carrier must be within limits
Most airlines do not allow dogs on laps during flights.
📏 Airline-Approved Dog Carrier Size Requirements
While exact rules vary by airline, most follow similar size limits:
| Dimension | Typical Maximum |
|---|---|
| Length | 18–19 inches |
| Width | 11–12 inches |
| Height | 10–11 inches |
Important Notes:
- Soft-sided carriers are preferred
- Flexible sides help fit under seats
- Hard-sided carriers are rarely allowed in-cabin
👉 Choosing the right airline-approved carrier is critical.
⚖️ Dog & Carrier Weight Limits
Most airlines set a combined weight limit (dog + carrier):
- Typical range: 15–20 lbs (6.8–9 kg)
- Weight is often checked at check-in
If your dog exceeds the limit, cabin travel may not be allowed.
🐾 Where Dogs Sit on the Plane
Dogs must be placed:
- Under the seat in front of you
- Never in exit rows or bulkhead seats
- Never in overhead bins
Window seats are often easier for fitting carriers.
📄 Required Documents for Flying With Dogs
Most airlines require:
- Up-to-date vaccination records
- Health certificate (sometimes required for longer flights)
- Reservation for your pet (limited spots per flight)
💡 Airlines typically allow only a limited number of pets per flight, so booking early is important.
🚫 Breed Restrictions (Important)
Some airlines restrict:
- Snub-nosed (brachycephalic) breeds
- Certain large or aggressive breeds
Restrictions are more common for cargo travel, but rules vary.
Always check airline-specific policies before booking.
🧳 Airport & Boarding Rules
At the airport:
- Dogs must remain in carriers
- You may be asked to remove your dog briefly during security screening
- Carriers go through the scanner; dogs are hand-carried through metal detectors
Arrive early to avoid stress.
😌 Tips for a Smooth Flight With Your Dog
- Choose early morning or late evening flights
- Avoid feeding right before flying
- Add a familiar blanket or toy
- Let your dog get used to the carrier beforehand
Calm preparation makes a big difference.
