That's why I am not really certain how much LOT+Asiana flight with 2 luggage piece would cost...
I think you misunderstand. Forget about Momondo for minute.
When you search for the price for flights WAW to Tokyo on the website of LH and LOT you will find fares that includes checked luggage (i.e. not the cheapest fare). I just had a look on the LOT website and a fare to Tokyo that included 2x 23 kg is only around 60 EUR more than the cheapest LOT fare to Tokyo (so it would be around 2x 60 EUR for return flight). So buying the cheapest LOT fare with an OTA from Momondo and adding 2 pcs of checked luggage will be more expensive than buying a ticket with checked luggage directly with LOT or LH (on their website).
