Southwest Florida's palm-lined runways feel a world away from Andalusia's orange-blossomed plazas, yet the journey between them has become surprisingly manageable for those willing to route smartly. There is no nonstop option, so business class from Fort Myers to Seville requires a connection—typically through Miami or Charlotte on American Airlines, or via London or Madrid on British Airways and Iberia. As a factual baseline: the most efficient itineraries pair an American Airlines domestic or transatlantic segment with a European partner flight, bringing total travel time to roughly 9.5 hours of air time plus connection, making a well-timed one-stop routing the practical standard for this city pair.
Having flown this corridor numerous times, I favor the Miami–Madrid–Seville routing via American and Iberia, since Iberia's A330 and A350 business class—with fully lie-flat seats and direct aisle access on the A350—offers a genuinely restful long-haul leg before the short Madrid-Seville hop on a regional jet. Alternatively, British Airways through London Heathrow gets you into their Club Suite on the 777 or A350, which delivers a private, door-equipped cabin that's arguably the most modern hard product among the three carriers serving this market. My insider tip: if connecting through Madrid, build in at least 90 minutes, as Iberia's transfer process from international arrivals to the domestic Seville gate isn't always intuitive, and missing that final leg means a long wait for the next flight.
Seasonality matters enormously here. April, May, September, and October are the sweet spot—not just for Andalusia's mild weather and feria season, but because business class award and fare availability tends to loosen up outside the sweltering Spanish summer and the winter holiday crunch. Given the route's complexity and the way fares fluctuate across three carriers and multiple hub options, this is exactly the kind of itinerary where setting up automated fare alerts pays dividends, letting you pounce the moment a premium seat opens up at a compelling rate rather than checking manually week after week.
