Ok. So I am booking my wife a reward ticket from Houston to Quito. The routing is CO to Panama City and Copa from Panama City to Quito. Coming back is also copa to PTY and CO to IAH. My wife has no status, I am a Plat. I am booking her coach from IAH-UIO and First UIO-IAH using my miles/account . However the first segment coming back on Copa (uio-pty) is in coach.

My question is in this mess what is she allowed for baggage (for free. number of pieces and weight) on each segment? The small taxes that are paid I paid with my co mastercard if that makes a difference.
