I searched, but cannot seem to find info that answers my question. Sorry if I missed a thread somewhere.

So, are fare classes Economy (E) and Economy (Z) categorized as 'Promo' or 'Economy' by Avianca Brasil? I found flights that I want on UA.com and they show as these fare classes; however, Avianca Brasil's website does not refer to the fare class, just these general categories of Promo, Economy, Flex, etc. for baggage fees on flights within Brazil.

If it falls into Economy, it appears I do not pay for one checked bag. If it falls into Promo, it appears I would pay for a checked bag.

Thank you.
