Airline pet policies are some of the most-changed pages on the internet. Carriers tweak fees quarterly, breed bans shift seasonally, and the official policy page on each airline’s site is full of legalese that most pet owners don’t have time to parse.
We track every major US airline’s pet policy and translate it into plain English: how much it costs, what kennels are allowed, whether your dog can fly in cabin or has to fly cargo, weight and breed restrictions, what paperwork you need at the gate. We verify against the airline’s own page every time we update the article — and we stamp the verification date clearly.
