Southwest Airlines is set to launch its first-ever transatlantic route, flying from Baltimore to Reykjavik in spring 2026. This marks a major milestone as the carrier steps beyond its U.S.-focused model using Boeing 737 MAX 8 aircraft. The airline will partner with Icelandair for interline services, allowing smooth baggage transfer and broader European access. Baltimore will serve as a key international gateway for this venture. Despite lacking premium long-haul amenities, Southwest sees Iceland as a low-risk starting point for international growth. Future expansion may depend on fleet adjustments or deeper international partnerships.
