Ibiza's tiny airport has no long-haul widebody service, which is precisely why the routing matters more than the destination on this itinerary. There is no nonstop option for business class from Fort Lauderdale to Ibiza, so the real decision happens at the connection: Madrid via Iberia, London via British Airways, or Frankfurt/Munich via Lufthansa, each requiring a short regional hop onto IBZ afterward. Iberia's A330 and A350 business class, with their reverse-herringbone seats and Level Alcázar lounge access in Madrid, makes for arguably the smoothest single-carrier journey, since Iberia also operates the connecting narrowbody to Ibiza in many summer schedules. British Airways routes through Heathrow Terminal 5 with Club Suite on its 777s and A350s, a genuine flat-bed product with direct aisle access, though the T5-to-T3/T5 domestic connection for the Ibiza leg needs a comfortable buffer given Heathrow's occasional congestion.
Lufthansa's option, transiting Frankfurt or Munich, brings the newer Allegris business seats into play on select long-haul aircraft, though not yet fleet-wide, so it's worth checking your specific equipment before booking if that seat is the deciding factor. My own preference after years flying this corridor is Madrid: the connection window is generous, Iberia's ground handling is dependable, and Barajas rarely feels chaotic even during peak Balearic season. One insider habit worth adopting — book the Ibiza feeder flight as a separate short-haul business fare only when the codeshare through-fare isn't materially cheaper, since IB and BA sometimes price the standalone hop lower than the bundled itinerary.
Seasonality here is sharper than most transatlantic routes because Ibiza itself is essentially closed to meaningful air service outside April through October. The sweet spot for value is the shoulder months — April, May, September, and October — when the island's energy is still vibrant but demand (and business class award space) eases considerably compared to July and August. Given how thin and seasonal capacity is on the Ibiza connecting legs, setting up fare alerts for this specific FLL–IBZ corridor is genuinely the smartest way to catch the rare premium-cabin deals before they vanish.
