There is no nonstop path between Southern California and Ibiza's compact seaside airport, which is precisely why the routing you choose matters as much as the seat you book. Business class from Los Angeles to Ibiza always requires a connection, and the three realistic carriers—Iberia, British Airways, and Lufthansa—each funnel you through a different European gateway before a short hop to IBZ. Iberia's Madrid connection is arguably the smoothest, pairing its A330neo business class with a same-terminal transfer at Barajas onto a quick regional flight; British Airways routes through Heathrow, where the Club Suite's direct-aisle-access seat and door make the long westbound leg genuinely restful; Lufthansa connects via Frankfurt or Munich, and if you're lucky enough to draw one of their Allegris-configured 787s or A350s, the new suite tiers are worth chasing even if it means a slightly longer layover.
Having flown this corridor repeatedly, I've learned that the Ibiza leg itself is the wildcard—these are short turboprop-adjacent or narrowbody hops with no business cabin, so the real luxury is banked entirely in the transatlantic segment. My insider tip: book the earliest Madrid or London connection you can find in shoulder season, because IBZ's single-runway airport gets congested with charter traffic by midday in peak summer, and a morning arrival avoids the worst of it—also, Iberia's Madrid lounge (the Dali) is a genuinely underrated place to shower and reset before the final descent into the island.
April, May, September, and October remain the sweet spot, not just for fares but for avoiding Ibiza's July-August congestion both in the air and on the ground. Given how much these fares swing with school holidays and event calendars on the island, setting up automated fare alerts is the smartest way to catch a premium seat before the window closes.
