Want to take your dog on the plane – and wondering what you need, what's allowed, and which bags will actually get through? We've compared airline rules, compiled the most common mistakes – and explain who ultimately decides whether your bag flies.

What you need to clarify before booking

Each airline has its own rules for dogs in the cabin. Before you book, you should check three things:

• Does my airline allow dogs in the cabin – and is there still space available? The number is often limited to two to four animals per flight.
• What dimensions and maximum weight (dog + bag together) are permitted?
• What are the entry requirements at the destination? Vaccination certificate, microchip, health certificate – these vary depending on the country.

It's best to call the airline directly. Not everything is up-to-date on the website, and the rules change occasionally.

Who decides whether your bag flies?

Many people believe there's a regulation that permits carry-on bags. There isn't. The IATA (International Air Transport Association) describes in detail in its Live Animals Regulations how a container for the cabin should be designed – dimensions, closure, base, ventilation. However, it doesn't certify any individual bag. This text only becomes legally binding through your airline's terms and conditions of carriage, and these vary considerably: some refer verbatim to the IATA rules, while others simply require a "ventilated, closable bag."

Whether the bag actually flies is decided at the gate by a person who interprets the conditions for that day. The same bag, the same airline, two airports – two decisions. Our customers experience this regularly, and it's not their fault.

The most frequent point of discussion is ventilation. IATA regulations are strict on this, while the terms and conditions of carriage of many airlines are considerably briefer. Only your airline's own terms and conditions will tell you where they stand.

Regarding the AIR: Mesh at the front extends almost to the ground and across the entire roof; the raised mesh is standard and removable. You can see how much air your dog is getting – and so can the gate attendant.

Left: With optional raised net – for dogs that need to stand upright. Right: Fully enclosed, ready for the gate.

Which AIR fits the requirements of which airline?

We have checked the dimensions and weight of our flight bags against the regulations of the most important European airlines. A ✓ means: within the size and weight limits. Please always double-check with your airline, as rules can change.

Size and weight specifications as of 2025, without guarantee. Only your airline can confirm whether your bag will be accepted.

The right bag: What really matters

The bag is the most important part of your flight. It not only has to meet airline size requirements – it also has to be suitable for your dog and fit in the footwell in front of you.

Fully lockable

All openings must be able to close completely – this is mandatory for almost all airlines. Our AIR bags have all-around zippers to ensure this.

Attachable to the trolley

All 4legs AIR bags can be attached to your suitcase with an integrated trolley strap. No more lugging it through the terminal – you push your suitcase and your dog rolls along comfortably.

Versatile: bag, basket and carry-on bag in one

Once you arrive at your destination, the mesh net can be removed – and the travel bag transforms into a cozy dog ​​bed. All bags are machine washable at 30 degrees.

How to get your dog ready to fly

The best bag is useless if your dog has never seen it. Familiarity is everything.

• Weeks in advance: Place the bag open in the apartment. Let the dog explore it on its own, put treats and its favorite blanket inside.
• Practice short trips: First a car ride, then a busy place, then a train station. Gradually get used to noises and people.
• Don't overfeed on the day of travel: Last meal at least 3-4 hours before departure. Offer water, but in moderation.
• Tired = relaxed: A long walk before the flight helps. Many dogs then sleep almost the entire time.
• Bring along something familiar: A small piece of blanket or a toy with a familiar scent can be calming on a plane.
• Stay calm: Your dog senses your nervousness. People who are relaxed themselves usually have a more relaxed dog.

At the airport: What to expect

• Check in early – with the airline, the dog often needs to be registered separately, either by phone or online.
• Keep your veterinary certificate and vaccination record handy – checks can happen even within the EU.
• At the security checkpoint: briefly take the dog out of the bag, have the bag x-rayed, then put the dog back in.
• Your bag must remain in the footwell in front of your seat for the entire flight. It must not be placed on your lap or in the overhead compartment.
• Have your airline's terms and conditions of carriage printed out and with you – and, if you called, the written confirmation. That's worth more at the gate than any argument.
