Nashville International Airport has expanded its network with the addition of two new long-haul airlines. On April 10, Icelandair commenced its service from Keflavik, Iceland, marking the airport's first-ever connection to Iceland. Two days later, on April 12, Aer Lingus will start its flights from Dublin, Ireland, adding a new link from Europe to the Tennessee city. This expansion brings the number of long-haul airlines operating from Nashville to three, including the existing British Airways services to London Heathrow.
Icelandair's debut in Nashville increases the airport's transatlantic capacity significantly. According to Cirium Diio data, the addition of Icelandair and Aer Lingus raises the capacity to 263,000 round-trip seats, marking a 51% increase from the previous year. However, despite the rise in transatlantic connections, European-bound seats still account for a small percentage of Nashville’s total seat offerings, with numbers slightly increasing during the peak summer months.
Icelandair, launching its service with a Boeing 737 MAX 8, will operate four weekly flights on a summer seasonal basis. The schedule sees departures from Keflavik at 17:10 on Mondays, Wednesdays, Fridays, and Sundays, arriving in Nashville at 19:30. The return flights leave Nashville at 20:55, reaching Keflavik the following day at 08:40.
