Jump Ahead: United Airlines Dog Policy Overview

Is United Airlines Pet Friendly?

First, is United Airlines pet friendly? According to our 2024 Sniffspot Travel Survey, traveling with dogs presents significant challenges for most pet parents. In fact, here's how they rate traveling with a pet vs. leading Fido at home:

• Similarly difficult 9%: A small number of pet parents find dog-travel to be similarly difficult to traditional travel.
• Less difficult 3%: Only a marginal number of users find traveling with dogs to be less difficult.
