Airlines That Allow Multiple Dogs: Options for Flying with Two Dogs In-Cabin

Chances are, if you’re reading this, you have two small dogs that you want to bring with you in an airline cabin. We’ve written about our experience flying with multiple dogs, and the number one question people ask is: what airline allows that? Luckily, there are a few airlines that allow passengers to fly with multiple dogs. Here’s the skinny on airlines and which will allow you to fly with more than one dog.

Before we dive in…

Here are a few things to keep in mind when flying with two dogs:

  • Airlines differ in their policies, and that includes their regulations on flying with multiple pets. Be sure to read through each policy to see which ones work for you.
  • If you’re flying with multiple pets, notify the airline regarding your pets as soon as possible – many airlines restrict the number of pets in cabin, and you want to ensure that your pets grab a spot.
  • Don’t worry if your dogs are different sizes – all is not lost! Some airlines will allow you to fly with two dogs in separate carriers.
