I have three flights (two connections) in my itinerary. The first two of them are Qatar Airways business class tickets, and they cover 95% of the entire journey. The last one is an American Airline (Operated by ENVOY AIR AS AMERICAN EAGLE), and it is an economy seat.
Qatar Airways allows me to carry two checked in items while American Airlines allows only one. This is what I've learnt from both these airlines' official websites.
Even though everything is in one ticket/itinerary, there are two different PNRs - one for both Qatar Airways flights and another one for American Airlines flight.
The ticket given by my online-travel-agent shows 2 pieces for all three flights individually, but this information is not shown when I enter my PNR in both Qatar and American Airlines' websites. Should I neglect that and carry my agent's ticket? It seems if things do go wrong, I might have to pay $100 for the 2nd piece.
NOTE: The last flight, American Airlines, is from Chicago to Ohio, hence it might count as a Domestic flight rather than an International connection flight. This is one of my doubts about the whole thing.
