There's a certain irony in routing through T.F. Green, a terminal small enough to clear security in minutes, en route to Andalusia's grandest cathedral city — yet that's precisely the appeal of booking business class from Providence to Seville. No carrier flies this pairing nonstop, so the real decision isn't whether to connect, but where: American Airlines routes travelers through its Philadelphia or JFK hubs before a transatlantic hop, while British Airways and Iberia funnel passengers through London Heathrow or Madrid, respectively. As a factual baseline, expect total journey times in the 12-15 hour range once you factor in connections, against a raw transatlantic flight time of roughly 8.5 hours.
My preference, after flying this corridor repeatedly, leans toward Iberia via Madrid. Their A330neo and A350 business class cabins offer proper lie-flat seats with direct aisle access, and landing in Madrid means a short domestic hop to Seville rather than navigating another country's customs twice. British Airways via Heathrow puts you in the Club Suite — a genuine game-changer with its door and stable work surface — but Heathrow's T5 connections can eat 90 minutes minimum if you're unfamiliar with the terminal's layout; I always budget extra time there. American Airlines, meanwhile, offers Flagship Business on its transatlantic legs from Philadelphia, a comfortable if less exclusive product, with easier same-alliance ticketing back to Providence.
Seasonally, April, May, September, and October reward patient travelers with the most favorable business class availability, as Andalusia's brutal summer heat suppresses leisure demand outside those shoulder months. My insider tip: book Iberia's Madrid connection with at least a 2-hour buffer, since Seville-bound regional flights depart from Terminal 4S, a satellite terminal requiring an internal train transfer many first-timers miss. Given how frequently award space and fares shift across these three carriers, setting up automated fare alerts for this specific routing is the smartest way to catch a premium seat before it disappears.
