Even if your Yorkie is not a service dog, flying shouldn't be a problem. I flew with my Joonie twice this month- once domestically from Chicago to Harrisburg, PA and once internationally from Harrisburg to Beijing, China.
United and Korean Air are the only two airlines that allow dogs to fly in-cabin (under the seat in front of you) internationally. I flew United and had no problem at all adding Joonie onto all my flights with me. The extra cost was $125 per flight. It's best to fly economy, because some business and first-class seats aren't set up to be able to slide a carrier in front of you. |
