Can My Dog Fly In Cabin?

Yes, regular pet dogs can fly in the cabin on most airlines — it's not just for service animals. You need to book with an airline that accepts pets on board, and your dog has to meet their size and weight requirements. The dog flies in an airline-approved carrier under the seat in front of you, and you pay a pet fee (typically €35–$200 per one-way flight). Our free airline PDF guide lists every pet-friendly airline and their rules.

There's no universal limit — it depends on the airline. Most European airlines cap it at 8 kg (17.6 lbs) including the carrier bag. Some allow up to 10 kg (ITA Airways, Volotea, Air Europa). US airlines like Delta, United, and American don't set a specific weight limit but your dog must fit comfortably in a carrier that fits under the seat. The strictest airlines (SUN-AIR, Vietnam Airlines) cap at 6 kg. You can compare all 51 airlines’ weight limits in our free PDF guide.

On most airlines, yes — the weight limit includes your dog plus the carrier. A typical soft carrier weighs 1–2 kg, so if the limit is 8 kg, your dog should ideally weigh no more than 6–7 kg. This is one of the most common mistakes first-time flyers make, so always weigh your dog and carrier together before heading to the airport. Our free 8-day email tips cover exactly how to handle this.

If your dog is too heavy at check-in, the airline may require them to travel in cargo instead of the cabin. In practice, it often depends on the check-in agent — some are lenient with dogs slightly over the limit, while others stick to the rules. In Europe, they almost always weigh the dog. In the US, they typically don't weigh but check that the dog fits well in the carrier. We share tips for handling this in our free flight prep emails.

Requirements vary by destination. Within Europe, you typically need a pet passport with a valid rabies vaccination and microchip. For flights into the US, dogs must be at least 6 months old, microchipped, and you'll need a CDC Dog Import Form. Always check both your airline's pet policy and the import rules of the country or state you're traveling to. We break down the full document checklist in our free daily email series.

Go with a soft-sided carrier — it's lighter (helping with weight limits) and flexible enough to fit under most seats. Check your airline's maximum carrier dimensions first (they vary). Look for at least two mesh sides for ventilation, a removable washable bottom, and multiple openings so your dog can peek out. When in doubt between sizes, go slightly larger rather than smaller. Our free PDF guide includes carrier size requirements for all 51 airlines.

Pet fees range from about €35 for short European flights to $200+ for transatlantic routes. The fee is per one-way flight, so a round trip means paying twice. Some budget airlines charge less (Volotea: €39, Aegean: €35–€65), while US carriers typically charge $100–$200. The fee is separate from your own ticket and usually paid at check-in or when booking.
