You are overestimating the appeal of Barcelona to Spanish-speaking Latin Americans, specially in a city where Spanish language is not particularly welcomed.

I can't find details specifically Mexicans (370,000 visited Spain in 2016), but according to the Spanish Statistical Office, in 2017 citizens for the Americas (other than US-citizens; so this figure includes Canadians that very likely visit BCN more) made 1.6 million overnight stays in Barcelona VS 2.4 million in Madrid. So Madrid is already way ahead of Barcelona as a tourism destination for Latin Americans. If you count VFR and specially business links MAD is in another galaxy.
There is a reason why MEX-MAD is currently 35 weekly and MEX-BCN is 0.
