Actually, I was able to do exactly what was suggested. I flew SFO-ICN on SQ and then on to Guam by KE. After landing in ICN, I was refused boarding on KE due to cabotage and had to spend one night in Seoul and board the next day (24 hours in Korea apparently solved the cabotage issue). Very annoying.
