Just completed my first ICN-USA rt in F (have booked 4). Flew outbound, ICN-DFW-PNS without any trouble. Return, PNS-DFW had a two hour mechanical and we missed the connecting flight to ICN. Called EXP line as soon as I knew I had to reroute. Agent was HORRIBLE. Would only confirm me on the next day, same flight. Hung up. Did some research, found the flights I would need to get me home. Called back. Spoon fed the agent the flights I wanted. She saw all were available, and booked me onto the flights (PNS-DFW-LAX (AA), LAX-ICN (KE)). Would only put me in Biz on KE flight. I argued I was on a purchased first class fare. Wouldn't budge. Had her book to get on flights. Went to agent at checkin in PNS (a TRUE ROCK STAR), explained I should be rebooked in first, and she did it!. Flew home no problems.
