Madrid to Atlanta - Delta's sole nonstop transatlantic from MAD to its home hub, running.
Delta operates a seasonal nonstop from Madrid Barajas to Atlanta Hartsfield-Jackson, typically running May through October. Outside this window, the best options route through JFK, Newark, or Philadelphia on Delta or its SkyTeam partners. Iberia offers connecting options via Miami or New York using its oneworld tie-ups with American Airlines.
The nonstop flight is approximately 10 hours westbound and 8.5 hours eastbound. During the active season, Delta uses its 767-300ER on the route. Fares peak during summer months (June-August) and around Thanksgiving-adjacent European travel. October - the final weeks of the nonstop season - regularly produces the route's lowest fares as airlines clear remaining inventory. Madrid to Atlanta fares move quickly, so flexible date checks usually save money.
For off-season travel (November-April), connecting through Iberia's Madrid hub onto a transatlantic partner flight is usually the most competitive option. One-stop routings via Lisbon (TAP) or Paris (Air France) can also undercut direct US carrier pricing during winter months. For Madrid - Atlanta, review carrier mix (Delta, Iberia (via hubs)) before choosing a fare bundle.
