OP should get allowance of the marketing segment if he first carrier throughout - I believe the international allowance should be allowed through the intro-EU legs. Being a trip from/to the US, the DOT rule on baggage would be used, which is the allowance of the marketing carrier of the first flight - presumably (thought this isn’t outright stated), it would be UAs. Note the rule doesn’t take into account FF status, but given its a through * partner anyway, it shouldn’t really be much of a stickeing point as LH will give the * allowance of Ann extra bag anyway.
