I bought two separate tix (MEM-DEN and DEN-MUC-CGN) with a 3.5 hour connex, because pricing. My plan is to ask the check-in agent at MEM if they can check my bag/s all the way through to my final destination, CGN. I know they can do that, if properly trained. Will completing app OLCI for either first or second tix mess things up on their back-end? Should I add checked bags to the OLCI flow on the UA app for either the first or second routing?
