Boston Bag AIR XL-LONG – Dog airline bag in melange fabric, extra long
The Boston is the "AIR" for those who want a travel bag that doesn't look like a travel bag – and the XL-LONG is the Boston for dogs who like to stretch out: 48 cm of interior length, plus an optional raised mesh panel. The exterior is made of a soft, salt and pepper melange fabric, like you'd expect from a good travel bag; inside, there's a reversible lining – one side is fluffy faux rabbit fur, the other velvety minky. It's hand-sewn in Hamburg, IATA-compliant, and weighs 1,320 grams. The grey mesh panel can be fully closed, as required by airlines, and removed after the flight – then the Boston is a bag you can take to a restaurant.
Two net heights – the choice is yours

The standard net sits flush with the bag – ideal for everyday use and for dogs who prefer to lie down while traveling. The raised net adds approximately 15 cm of height: Many airlines require that the dog can stand, stretch, and turn around in the bag – this is exactly what the raised net allows, addressing the airline's most common objection. As an added bonus, your dog will enjoy more space and a better view. Choosing the raised net also includes the standard net – the raised one for flights, the standard one for everyday use. You can select the net height using the "Net" option at the top.

Will your dog fit inside?
The XL-LONG has an interior length of 48 cm – six centimeters more than the XL. This is the bag for dogs with long backs who like to stretch out, and for anyone who prefers a comfortable fit over a snug fit. The crucial factor is your dog's lying length, not its weight – weight is only relevant for airline regulations.
Here's how to check in a minute: Measure your dog, curled up or lying on its side, from nose to rear. If it fits within 48 cm with a little wiggle room, the XL-LONG will fit. And if your dog is tall or long-legged – Italian Greyhound, Toy Poodle – add the raised mesh: 15 cm more headroom so it can stand up and turn around in the closed bag, as many airlines require.

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; the AIR carrier, at 23 cm, is three centimeters larger. KLM and Air France (46 × 28 × 24 cm) are too small for the AIR carrier.Whether a bag is allowed on the day of the flight is ultimately decided by the ground staff – the airline is IATA-compliant, but no airline grants a formal approval in the true sense.

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 Boston Bag AIR XL-LONG offers your dog a comfortable, safe, and durable transport solution.
