What folks are asking is whether you bought this has one ticket from the online TravelAgent or bought two or more separate tickets. For example is this two one-way tickets or a round-trip ticket? Or is one leg of the journey one ticket and the next segment is a different ticket? That will be a big help in determining what the baggage rules are.You may have two PNR numbers as each airline generally has its own for the same flight/ticket. That does not mean you have separate tickets.
