Icelandair’s New Longest A321LR Route: Miami Launch Kicks Off Winter Switch

Icelandair will stretch the legs of its Airbus A321LR fleet next week with the launch of nonstop service between Keflavík (KEF) and Miami (MIA), timed with the IATA winter schedule change on Sunday, October 26. The South Florida link, last served from Iceland by WOW air in 2017–2018, becomes Icelandair’s longest A321LR flight by block time at up to 8 hours 40 minutes westbound.
A long, lean way to Florida
Rather than deploying a widebody as WOW did, Icelandair is betting on the transatlantic sweet spot: a high-efficiency narrowbody with long legs and lower trip costs. The carrier’s A321LRs seat 187 passengers—22 in Saga Premium recliners (2-2, ~42” pitch) and 165 in economy (3-3, ~31”). Three weekly roundtrips are planned through winter, with an evening arrival and next-day late-afternoon departure in Miami to maximize both Europe-bound and U.S.-bound connections via KEF’s tight banking structure.

KEF → MIA: Tue/Thu/Sat, dep 17:15, arr 20:55 (8h40m max block)
-
MIA → KEF: Wed/Fri/Sun, dep 17:15, arr 05:55+1 (7h40m)
The aircraft night-stops in Miami, a necessity given stage length and bank connectivity. That also cushions against winter weather variability while preserving the eastbound red-eye timing that feeds morning arrivals across Europe.
Why Miami—and why now
Florida has been a bright spot for transatlantic leisure demand, and Icelandair’s move brings the state back to two airports in its network for the first time since Tampa ended in 2019. Miami complements Orlando, which previously held the airline’s longest-by-time distinction (8h20m). With the A321LR, Icelandair can right-size capacity for a highly seasonal market without the risk of flying half-empty widebodies in shoulder months.
Operationally, the route fits the A321LR’s profile: long but not extreme, warm-weather destination appeal in winter, and strong onward connectivity on both sides. In Iceland, Miami’s overnight arrival dovetails with early-morning Europe banks to cities like London, Paris, Amsterdam, Copenhagen, and Berlin; in Miami, the late afternoon departure caters to South Florida’s sizable Europe-bound leisure segment and increasingly diversified inbound tourism.
Network implications
Miami’s addition reshuffles Icelandair’s “longest missions by time,” a list otherwise dominated by U.S. West Coast and Mountain West stations:
-
KEF–MIA (8h40m)
-
KEF–MCO (8h20m)
-
KEF–PDX / KEF–DEN / KEF–SEA (~8h00–8h10m)
Across winter, the A321LR will also see heavy duty on Seattle, operating daily through late March before ramping briefly to twice daily in late March and then giving way to other fleet types as summer redeployments kick in. Expect New York JFK and Newark to reclaim much of the narrowbody long-haul capacity heading into the shoulder.
Product & experience
Icelandair’s A321LR brings a consistent hard product to a long narrowbody sector:
-
Saga Premium: 22 recliners with wide seats, large pitch, enhanced dining, checked bag allowance, lounge access on eligible fares, and priority services. It’s not a lie-flat seat, but on a sub-nine-hour sector many leisure travelers will trade a bed for lower fares and sensible timings.
-
Economy: 165 seats with personal device holders, power at most seats, and a solid on-board entertainment selection via seatback or streaming (aircraft-specific). Paid Wi-Fi plans are typically available; meal service varies by fare and sector length, with buy-on-board enhancements common.
The LR’s lower cabin altitude and quieter interior versus older narrowbodies should make the long westbound more comfortable, while the red-eye eastbound lands in KEF in time for early Europe connections.
Competitive landscape
Miami–Iceland saw WOW air’s A330-300 briefly, but Icelandair’s strategy is markedly different. Rather than filling a large widebody with highly seasonal demand, the carrier is leaning into the hub-and-spoke KEF model: a mid-size cabin fed by dozens of European spokes and, to a lesser degree, U.S. connect traffic. Miami also broadens Icelandair’s South Florida footprint alongside Orlando, where the airline has performed well across family and theme-park travel.
Looking ahead, the A321XLR—due later in the decade—will extend Icelandair’s single-aisle reach even further (think deeper South, Central America, or additional U.S. Southeast and Texas points), while keeping trip costs tightly aligned with off-peak demand.
Bottom Line
Icelandair’s Miami launch is a textbook A321LR play: long enough to need LR range, leisure-heavy enough to shun a widebody in winter, and precisely timed to plug KEF’s banks. At 8 hours 40 minutes, it becomes the carrier’s longest flight by time, edging Orlando and several West Coast services. For travelers, it offers a one-stop gateway to much of Europe and a fresh, right-sized option to South Florida as transatlantic schedules pivot to winter.
