Flights with an origin or destination of the USA follow the First Marketing Carrier rule, although the marketing carrier is allowed to delegate to the Most Significant Carrier. In this case, it’s UA either way. However, the credit card waiver explicitly only applies when checking in with UA. The DOT rule does not require that any waivers carry across, just the underlying fees. So, if UA says “we don’t charge for bags,” then LX can’t charge for them. But if they say “we charge $5,000 for each bag, but we waive that fee for all customers except our own CEO,” then LX may charge $5,000. (In practice, they’d be allowed to charge their own fees instead, provided that this resulted in a savings to the customer).
essentially, it’s what the fare dictates, and is coded into the ticket. That’s what LX will see and charge.
if it was a *G, for example, instead of based on credit card, OP would get the 70lb. Free bag on outbound, and would get a 50lb bag on return (as elite benefits don’t factor into the rule either, so you’d get LX *G allowance on return, not UAs which has a waiver for the heavier weight)
