Business Class from Phoenix to Granada
Business class fares from Phoenix to Granada run $2,750–$6,800 round-trip through BestBusinessClass.com, with itineraries built around a connection at Dallas-Fort Worth, Charlotte, Atlanta, Minneapolis, London Heathrow, or Paris CDG since Granada's small regional airport (GRX) has no direct long-haul service and Phoenix itself isn't a widebody gateway. Total travel time typically lands around 12 hours of flying, but with a connection or two, plan on 15-18 hours door to door depending on layover length. That connection actually works in your favor for comfort: you get a proper lie-flat long-haul segment across the Atlantic, then a shorter regional hop into southern Spain (often via Madrid or Barcelona before the final puddle-jump to Granada).
