Transporting a dog in the airplane cabin: what you need to know before the flight

You can bring a pet into the aircraft cabin on almost every European airline. But the rules vary by carrier, and they determine whether your dog flies next to you or in the cargo hold.

The main restriction concerns the weight of the pet together with the carrier (as of 09/2026, Lufthansa rules). A small pet usually fits within the limit, while a large dog flies in the cargo hold. Below you will find answers to five frequently asked questions: what to bring on the flight, which airlines allow dogs on board, how much they can weigh, how to book a spot, and what rules apply in Europe.

What to bring with you when flying with a dog

💡 In short:

• Prepare the pet passport: microchip, rabies vaccination, veterinarian stamps.
• Buy a hard carrier that fits under the seat and a spill-proof water bowl.
• Arrange pet transport in advance, when you buy your ticket.
• Rules and fares: 09/2026, verified on the official airBaltic website.

Start with the paperwork. You will need a pet passport with a microchip record and a valid rabies vaccination. Under airBaltic rules, the animal must be at least 15 weeks old at the time of departure (as of 09/2026, airBaltic). The vaccination must be given well in advance. Do not put off the vet visit until the last week before your trip.

Next, you need a carrier. For the cabin, a hard-sided bag that fits under the seat in front of you works. At airBaltic, its dimensions must not exceed 55 by 40 by 23 centimeters (as of 09/2026, official requirements). The bag must be closed, waterproof, and ventilated, otherwise it will not be accepted at the check-in counter.

Do not bring a huge crate or a cramped bag. The animal must be able to stand at full height, turn around, and lie down. Add a spill-proof water bowl: many airlines require this. It gives you peace of mind and helps your dog handle the flight more easily.

Contact the carrier before buying your ticket. Each flight has a limited number of animals allowed, so the booking must be confirmed in advance. airBaltic charges €70 for cabin transport one way (as of 09/2026, airBaltic fares). We have compiled the requirements of different airlines in our article.

Which airlines do not allow dogs in the cabin

Most carriers allow a small pet in the cabin. But budget airlines have stricter rules, and there the dog flies in the cargo hold or does not fly at all. Ryanair does not transport animals at all, except for guide dogs (as of 09/2026, Ryanair).

Wizz Air and easyJet only allow an assistance dog in the cabin that accompanies a passenger. If flying next to your pet matters to you, these airlines are immediately off the list.

The table answers a common question, but choosing a carrier does not end there. You can compare tickets for European flights on Kiwi.com.

How much can a dog and carrier weigh

Almost all European airlines keep a shared limit of 8 kg. That includes both the animal and the carrier. Lufthansa and airBaltic work this way, and you already saw the limit in the table (as of 09/2026, official Lufthansa website).

Some carriers calculate it differently. For example, Air Europa and Cyprus Airways look only at the weight of the animal itself. In that case the carrier does not count, and the total weight ends up higher. For you, that is a chance to bring a pet that would have gone over the limit with the bag long ago.

A few companies have a limit above the general norm. La Compagnie has the most generous terms, but it flies only business class and only between a few cities in Europe and the US (as of 09/2026, La Compagnie). Transavia, in turn, has dropped its previous restriction. Check the rules again before every flight.

The takeaway is simple. Before buying a ticket, ask the carrier what exactly it weighs: the dog or the dog together with the bag. Whether your pet gets into the cabin often depends on that answer.

Is there a minimum weight for a dog

A lower threshold does exist. A number of European carriers will not take a dog that is too light into the cabin: the pet must fit the size of its carrier.

That list includes AnadoluJet, British Airways on certain flights, Bulgaria Air, Chair Airlines, Corsair, Helvetic Airways, and Twin Jet. Their threshold is not high, but check it on the company's official website before departure. Otherwise you risk finding out about the minimum only at the check-in desk.

Can you book a separate seat for a dog

Most European airlines do not offer such a seat. Under their rules, a dog flies in a carrier under the seat, not in its own chair. But exceptions exist, and they are worth asking about in advance.

If a company allows a separate seat, the service is arranged through the call center or chat on the website. They will tell you which flights are available and under what conditions.

General rules for flying with a dog in Europe

To make your first flight with a dog go smoothly, study the general rules in advance. They are the same for most carriers.

• To the UK and Iceland, a dog flies only in the cargo hold; the cabin is closed to it.
• In business class, pets are often not allowed because of the seat design.
• Tickets are cheaper to buy in advance, but not all companies sell a spot for an animal online.
• The rules are worth rechecking both before booking and before the flight itself.

For a first-timer, it is useful to read tips for a first flight and then compare them with your airline's policy. That way you will not end up at the gate with an animal that will not be allowed on board.

⁉️🤔 Frequently asked questions

Can I take a dog into the airplane cabin?

Yes, if the pet is small and passes the weight limit together with its carrier. The general norm for most European carriers stays around 8 kg, and that includes the bag (as of 09/2026, limits at Lufthansa). A large dog is sent to the cargo hold.

How much does it cost to carry a dog in the cabin?

The price depends on the airline and the route. With airBaltic it is a fixed one-way transport fee; with other carriers the amount is tied to the flight (airBaltic official website). Payment is usually made online or at the counter.

What if the dog weighs more than the limit?

Then the cabin is off limits, and the cargo hold is the only option. Large animals are transported in a rigid container that fits the size requirements. Before that, check the rules of the specific airline: container requirements and weight limits vary.

Do I need a separate booking for a pet?

Yes, transport must be confirmed in advance. A spot for the dog is booked together with the ticket or right after purchase. Without a booking, you may not be allowed on board.

Will a dog be allowed in the cabin on a flight to the UK?

No, the UK and Iceland require dogs to travel in the cargo hold. This rule applies regardless of the airline. So for these routes, allow time for checking in the animal and check the documents.

In short: what is worth booking

The five questions come down to three decisions: documents, carrier, and booking. If you have a small pet and a flight within Europe, choose an airline that allows dogs in the cabin and book a spot in advance.

The matrix is simple. If the dog and carrier together are within the weight limit, choose a carrier with an open cabin policy. If the pet is larger, prepare a rigid container for the cargo hold.

Hotels that allow dogs are easy to find on Trip.com, tours for your trip can be found on GetYourGuide, and insurance options can be compared on a dedicated page.
