Hi - I'm looking to book with miles a one-way ticket MCO>EWR>MAD on UA. Right now it's in Y for MCO>EWR (no F availability) and C for EWR>MAD. As I have a bag that's about 60lbs, and I have no status on UA, I'm wondering if the agent in MCO can charge me an excess bag charge even though I'm travelling in C on the international leg. Anyone know anything definitive about this? Thank you.
