There's no nonstop way to bridge the Georgia Lowcountry to Andalusia, which is precisely why routing strategy matters more here than on almost any other transatlantic itinerary I track. Business class from Savannah to Seville always requires at least one connection, and the most reliable path funnels through either Charlotte or Philadelphia on American, then across the Atlantic to a European gateway before a short hop into Seville's compact San Pablo Airport. In practice, I've had the smoothest experience routing via London Heathrow on British Airways, transferring onto Iberia's Madrid or Barcelona service for the final leg into SVQ, since Iberia maintains far more frequent intra-Spain connectivity than trying to force a same-day American Airlines connection through a secondary European hub.
For the transatlantic segment itself, American's Flagship Business on the 777-200 or 787-9 remains a dependable choice out of Charlotte or Philadelphia, with lie-flat seats and decent Flagship Lounge access at PHL. But if your dates allow flexibility, British Airways' Club Suite—now rolling out fleet-wide on select 777s and A350s—offers a genuine door and more privacy than American's older Flagship cabins, making the Heathrow routing worth the extra connection time. Iberia's A330 and A350 business class, with fully flat seats and decent Spanish wine lists, is a pleasant way to close out the journey once you're within Spain, and their lounge in Madrid's T4 is worth lingering in if your layover allows.
One insider tip: because Seville's airport has limited daily arrivals from major hubs, build in at least a two-hour connection buffer in Madrid or London during peak spring bullfighting and Feria season crowds in April and May, when local air traffic surges and ground handling slows. April, May, September, and October remain the sweet spot for both weather and fare value, avoiding the brutal Andalusian summer heat entirely. Given how thin premium inventory is on this corridor, setting up fare alerts is genuinely the smartest way to catch the rare moments when Iberia or BA release discounted business awards or cash fares before they vanish.
