GOL is actually selling seats from MCO to SDQ. In fact, they sell seats all the way down to Brasil, Sao Paolo, etc. The flights are GOL 737's, not the Atlanta-based code share partner's planes. The future of international flying is already going to the foreign carriers whom have lower costs, whether in hourly crew rates, or ticket is sold in USD$, but the crews are paid in a cheaper local currency, like brasilian reals or chinese RMB.
