Air-Custom dog carrier – your AIR, exactly the way you want it
The AIR-CUSTOM is the one and only "AIR": You choose the outer fabric, lining, shoulder strap, zipper, mesh, logo embroidery, and size yourself – in seven steps, and in the end, the bag is sewn by hand right here in Hamburg. Everything that makes the AIR special remains: meets the requirements of most airlines, The large mesh area for complete closure, the removable base, the internal hook, the side pocket, and the attachment to a rolling suitcase. Available as AIR XL-LONG and as
For warm days and southern destinations, the inner lining is now available in terry cloth, woven from 40% bamboo, 40% cotton, and 20% polyester. Terry cloth feels noticeably cooler than the fluffy Minky fabric and absorbs moisture – ensuring your dog stays comfortable even in summer. Both options can be found in the inner lining selection.
Will your dog fit inside?
Two sizes are available. The XL-LONG, with an interior length of 48 cm, is the bag for dogs with long backs up to approximately 7 kg; the EURO, with 55 cm, meets the maximum dimensions specified by airlines such as Lufthansa and Eurowings for cabin carriers and accommodates dogs up to approximately 8 kg, including the combined weight of the dog and carrier. The crucial factor is your dog's lying length: measure them from nose to rear end when they are curled up or lying on their side. If they lie comfortably in 48 cm, the XL-LONG is sufficient; if they need more space, the EURO is the right choice. Tall or long-legged dogs benefit from the raised mesh, providing more headroom so they can stand up and turn around inside the closed carrier.
| Size | Internal dimensions W × L × H | For dogs up to | Weight of the bag |
|---|---|---|---|
| AIR XL-LONG | 23 × 48 × 38 cm with raised net: 53 cm height |
approx. 7 kg | 1,150 g with raised mesh: 1,180 g |
| 23 × 55 × 39 cm with raised net: 51 cm height |
approx. 8 kg (dog and bag) | 1,360 g with raised mesh: 1,400 g |
All bags are sewn by hand; dimensions may vary by up to 2 cm, and weight by ± 50 g. A bag with terry cloth lining weighs a few grams less than one with minky fabric. The stated external dimensions will not be exceeded.
In the bag guide, we show you which size is suitable for your dog's weight, back length, and resting position.
To the pocket guideFor which airlines and for whom
The Lufthansa Group (Lufthansa, Austrian, SWISS), Eurowings, and Condor all specify the same maximum dimensions for pets in the cabin: 55 × 40 × 23 cm, a maximum weight of 8 kg for the dog and carrier combined, and the dog must be able to lie down and turn around in the closed carrier. All AIR carrier sizes are built to these dimensions – the EURO fully meets them, while L, XL, and XL-LONG remain below them. TUIfly specifies 55 × 40 × 20 cm, with AIR's 23 cm being three centimeters larger. KLM and Air France (46 × 28 × 24 cm) are too small for AIR. Ultimately, the ground staff decides whether a carrier is allowed on the day of the flight – AIR meets the requirements of most airlines, No airline actually grants a license in the true sense of the word.As of August 2026; you can find the current conditions at Lufthansa, Austrian, SWISS, Eurowings and Condor.

Instructions for using the bag
Our dog carriers are designed with a secure zipper and a sturdy mesh closure to keep your dog safe during travel. However, the carrier is not a place for your dog to be left unattended.
Puppies and young dogs especially have a strong urge to chew and tend to nibble on zippers, seams, or mesh areas. These parts are not designed for prolonged stress or chewing and can be damaged. Please never leave your dog unattended in the closed bag.
Should your dog start chewing on the material or fasteners, open the bag immediately and stop the behavior. Damage caused by chewing or improper use is not covered by our warranty (§§ 434, 276, 280 BGB).
The owner is responsible for the safe use of the bag. When used correctly, the AIR-CUSTOM offers your dog a comfortable, safe, and durable transport solution.
