I need help understanding the baggage allowance thing and if it will apply to me. I will be flying a route like LAS-ORD-AMS-FRA. The AMS-FRA is on LH but the same day as all the United flights. Do I have to recheck my bags according to LH's baggage rules in AMS when I clear Customs and Immigration or will I just drop it off and not have to worry about it?

Thanks in advance.
