Thanks very much. By any chance, do you know Copa's hours at SJO? I assume I'll need to collect my bag from United, clear customs and immigration, and then check my bag with Copa for the SJO-PTY flight. Hoping I can check in at 9:00 pm or 10:00 pm and not have to deal with my bag overnight, but that might not be possible. (The flight to PTY is at 4:00 am.) Thanks again.
