Multifunctional Portable Pet Bag/Cat Bag Size Guide
How to determine the right size pet bag/pet outing bag/cat bag (Hong Kong)
To determine the right cat carrier, we must first know the size, height, and length of the pet cat, because weight sometimes does not reflect volume .
Can pets travel on a plane with passengers? Can a cat be brought on board in a carrier?
Many guests have asked if we have in-cabin bags/cat bags that allow pets to travel with passengers. If the flight allows pets to travel in the cabin, you should check with the airline, as the size of each aircraft is different, and the size of the space under the seat also varies.
If your pet is a regular pet, the airline will arrange for it to travel as cargo. Some airlines allow them to be carried on board as checked baggage, while others require them to be transported as cargo and cannot be carried as checked baggage.
Please note the following before purchasing:
Pets Thing cannot guarantee that our handbags will be allowed on board. Customers need to check with the airline beforehand and make their own decision. We will not be responsible for any consequences.
Please measure the required dimensions carefully. We regret that we cannot accept exchanges, returns, or refunds based on product size discrepancies after purchase.
If you are traveling by air, we recommend that you contact the relevant airline before your trip to confirm their specific requirements. Returns and exchanges will not be accepted for reasons that the airline refuses to comply.
Space for pets on airplanes is limited; the number of pets allowed depends on the type of aircraft, destination, and operating airline. Please book your pet as soon as possible after booking your flight. Bookings should be made no later than 48 hours before flight departure.

KML Airlines
- When traveling in economy class or business class within Europe, you may bring one cat or dog into the cabin.

The total weight of your pet, travel carrier, or pet transport crate must not exceed 8 kg. Pets are not allowed to be removed from the pet transport crate during the flight, so please ensure your pet is small enough to move around comfortably.
