Icelandair's seasonal nonstop between Fort Lauderdale and Keflavík remains one of the more curious gaps in the transatlantic map, since most premium travelers assume they need to route through New York or Boston to reach Iceland in comfort. In truth, there is no scheduled nonstop business class from Fort Lauderdale to Reykjavík year-round — Icelandair (FI) has historically operated FLL–KEF seasonally, typically in the warmer months, and when it runs, it does so on the 757 or 767 with Icelandair Saga Premium, a well-padded recliner rather than a fully flat suite. For travelers who want a lie-flat product on this city pair, the more dependable play is connecting through Delta's Atlanta or JFK hubs, or United's Newark gateway, both of which feed into their own nonstop KEF services using Delta One suites (on A330/A350 equipment out of JFK) or United Polaris seats, with a short northbound hop that keeps total travel time surprisingly efficient given the direct routing avoids European congestion.
Having flown this corridor across several seasons, I've found the connection strategy matters as much as the cabin choice: routing through JFK on Delta lets you clear TSA PreCheck and international security in one pass at FLL, then enjoy a proper Delta One hard product for the long leg, which beats slogging through a European hub with a tight layover. If Icelandair's seasonal FLL–KEF metal is flying when you want to travel, book it for the novelty and daylight-hour arrival into Keflavík, but temper expectations on hard product versus Saga Premium's angled-flat seat.
May through September is when both capacity and pricing align best, as Icelandair ramps up seasonal frequencies and the Delta/United connecting itineraries see competitive business class fares against strong Icelandic tourism demand. Given how much this route's availability shifts with Icelandair's seasonal scheduling, setting fare alerts across all three carriers is the smartest way to catch a premium seat before inventory tightens.
