How MIA–GRU gets cheaper
- Regional point-of-sale pricing: the same flight is often filed at different tariffs in different countries and currencies. How it works.
- Split-hub routing: pricing MIA to a competitive hub and that hub to GRU as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: Revenue management releases inventory in sequential booking‑bucket waves, initially offering the cheapest split‑hub fare, then gradually tightening availability as the departure date approaches.
- Nearby airports: departing from FLL (Fort Lauderdale-Hollywood), or arriving at GIG (Rio de Janeiro Galeão), can change the fare.
