LAS-YYC (flight operated by Westjet, AA (codeshare) flight number) 3 nights in YYC
YYC-LHR-AMS (BA flights)

All booked at the same time in one itinerary, but I was given two reservation codes (one BA, one AA).

At the time of booking one of the screens mentioned "no additional baggage fees" or something similar in Dutch, however I doubt if this is true for the entire itinerary.

Does anyone know if I can check one bag (<23kg) for free on every flight of this itinerary, or should I expect to pay baggage fees for the JFK-LAS and/or LAS-YYC legs?

Thanks in advance.
