Iberia has a hub in Miami connecting to Central America and Mexico. Nothing grand. Just a mere 64 flights a week, but the second largest operation of a non-North American airline at a single airport in the US (second to BA at JFK) and the only non-US airline with a US hub. Like I said, currently, nothing grand. Though that is mostly because IB is currently operating the most flights it can between MIA and Madrid (10 742/3 and 4 A340 flights a week, plus 7 AA 763 codeshares). Once some treaties are worked out betwen Spain and the US (hopefully by this fall), and IB can add more flights, there are rumous IB will be in for major expansion, including possible services from MIA to Santo Domingo and Monterrey, Mexico, among other cities, as well as more Miami-based planes (currently 4 Miami-based A319s), possibly A320s. If your lucky, you will see all four Miami-based A319s in Miami surrounding their 747. Beautiful sight. The 747 surrounded by a pair of A319s on each side (IB's five gates are all next to each other). Also, AF's Miami-based 737 is gone. Replaced just a few weeks ago with a much nicer A320. They also use two Air Caribes-owned ERJ-145s (one is in AF colours, the other is not).
