Icelandair transitions Keflavik-Seattle route entirely to Airbus A321LR

Flightradar24 reported that Seattle first welcomed Icelandair's A321LR on May 20 when it replaced a larger capacity Boeing model. Despite covering a distance of over 3,000 nautical miles each way with up to eight hours of block time to reach the US West Coast, economy class does not offer inclusive meals.

The new summer schedule includes three daily flights from Keflavik to Seattle and back:

- FI685: Departs at 10:30 AM arriving at Seattle at 11:25 AM

- FI680: Leaves Seattle at 3:45 PM reaching Keflavik by next day morning

- FI681: Takes off at Keflavik at 4:50 PM landing in Seattle at 5:50 PM

- FI682: Departs from Seattle at 7:00 PM arriving in Keflavik next day morning

- FI683 & FI684 follow similar schedules

Increased flight frequency during summer means that overnight stays in Seattle are no longer necessary for connecting European routes. This adjustment helps reduce costs while maximizing aircraft usage.

Data from March 2024 to February 2025 shows that Icelandair transported nearly 199,000 passengers round-trip between Keflavik and Seattle, making it their second most popular US route after Boston. Approximately half of these passengers connected through Keflavik onto other destinations such as Copenhagen and London Heathrow.

Icelandair plans further deployment of its A321LR on other long-haul routes throughout the year including new services to Portland starting October and Miami later that month.
