Icelandair extends Nashville flights due to high demand

Icelandair has extended its service to Nashville International Airport through early January 2026, indicating strong demand for transatlantic flights. The airline will now operate flights to Nashville until January 4, 2026, with three weekly flights during November and December 2025. This extension comes before the route even begins on May 16, 2025, and is likely due to a successful partnership with Southwest Airlines. Icelandair will use Boeing 737 MAX 8 aircraft on the route, and the partnership with Southwest Airlines allows for connections to other US cities.
