Granada pulls travelers for the Alhambra, the Albaicín's narrow streets, and a slower pace than Madrid or Barcelona, but getting there in business class means picking your connection carefully. American Airlines routes through its Flagship Business cabin with a 1-2-1 lie-flat suite, Casper bedding, and Flagship Lounge access on the Miami end — a strong choice if you're already earning AAdvantage miles or want a familiar US carrier experience before transferring to a European partner into Granada or nearby Málaga. British Airways' Club Suite is the standout hard product here, with a sliding door for privacy and White Company linens, typically connecting through London before a short hop south. Lufthansa's newer Allegris suites on the A350 bring genuinely private pods and the airline's characteristic precision, routing through Frankfurt or Munich. Iberia makes sense for anyone who wants a one-stop feel through Madrid, with lie-flat 1-2-1 seating and a menu leaning into Spanish gastronomy that sets the tone for the trip ahead. Turkish Airlines, connecting through Istanbul, is often the value play — DO&CO catering is genuinely excellent, and the Istanbul lounge is one of the best in the world, though the routing adds flight time for those coming from the US.
