I believe somewhere around 20% of Miami's non-Hispanic white population is Jewish, which is an insanely high number for anywhere. As is, including all races and nationalities, the region is approximately 10% Jewish.

The local market on MIA-BUD is actually large enough (Budapest's third largest trans-Atlantic market after NYC and Toronto; probably because there is a large Hungarian community in Fort Lauderdale/Hallandale and the popularity of South Florida as a vacation destination for wealthy Eastern Europeans), that a 2-3w service, combined with the feed on both ends, is probably feasible. But that is still a good 4-5 years away. Let AA/MA develop Budapest as a better Central European hub, first, and ORD/MIA could feasibly join JFK in the much more distant future.
