I probably should have explained further. I have a flight booked AAA-BBB(8 day layover)-CCC(4 day layover)-AAA, all on American. I am based in BBB. My original plan was to get to AAA on a refundable one way that I bought a while ago, and home on a one way award ticket. My plans have changed a bit, so now I am looking at a RT Iberia ticket that would get me to AAA about 5 days (with a Sat. night) before the start of the multi city and back home about 4 days after the last leg of the multi city. So the entire multi city ticket would be nested within the RT. It wasn't my intention to cheat anybody, but I also don't want to get into any trouble.
