Both outbound and inbound flights are marketed by LH. OB first flight is UA, IB first flight is XQ. Ticket shows I have 2 bag allowance both for OB and IB.
UA (OB) agent last year demanded $100, but XQ (IB) agent just knew the rules and allowed me 2 bags.
As you say, UA agent was wrong, verified by LH customer service and a knowledgeable UA CSR. My question is: Do you have any suggestions if I end up with a non-knowing agent at the checkin counter again this year? Talk to manager? Call UA customer service?
