- Hello, The United Airlines Sydney Office was very supportive when I traveled with my pet. The staff explained the pet travel rules clearly and helped me with all the paperwork. They guided me on the crate size, food, and safety instructions for my pet’s journey. I felt relaxed because they treated my pet’s comfort as a priority. The process was smooth, and my pet reached safely. Overall, it was a caring and professional experience. for more information visit: https://rightcheckin.com/airlines/united-airlines-sydney-office-in-australia/
