Hello, I am planning to visit my sister that is stationed in Guam. I went to South Korea two years ago and loved the country so we decided to fly into south korea so on the way back to the states, we can spent 12 hours there exploring and seeing south korea. My sister mentioned the cabotage law and I am extremely lost because I have never heard of this before and I have spent too many hours researching this with no clear answer.

We would be flying from Cleveland OH to ICN via Air Canada, then from ICN to Guam via Asiana, then back to ICN via Asiana, spending 12 hours there then flying back to Cleveland, OH via Air Canada.

Is this cabotage? Thanks so much for your help!
