There is something quietly cinematic about the moment Newark's industrial sprawl gives way to the North Atlantic on a clear evening departure — and for those who know this routing well, booking business class from Newark to Reykjavík is one of transatlantic aviation's more underappreciated decisions. United Airlines and Icelandair are the two carriers operating this corridor, and between them they offer meaningfully different experiences worth understanding before you commit. United operates its Polaris business class product on this route, featuring its signature lie-flat seat with direct aisle access — a genuine luxury on a flight that, at roughly five and a half hours, sits in that awkward middle zone where you want real sleep infrastructure but the block time doesn't always justify a full night's rest. Icelandair, by contrast, does not operate a traditional lie-flat cabin on transatlantic routes; its Saga Class product offers a more upright premium experience, though the carrier compensates with strong Scandinavian-inflected service and exceptional value during shoulder-season windows.
The best fares on this route consistently surface between May and September, which conveniently aligns with Iceland's extraordinary summer light — a detail that matters more than people expect, since arriving into Keflavík at what feels like midday even at midnight recalibrates your body clock in ways that make a proper flat bed on the outbound genuinely useful. Newark's Terminal C is United's home turf, and arriving early enough to access the United Club before departure pays dividends on evening flights when the lounge crowd thins considerably after seven. One insider move seasoned travelers on this route have quietly adopted: positioning a Polaris seat on the left side of the cabin captures the most dramatic coastal Greenland ice-shelf views during daylight crossings in summer — something no inflight map adequately prepares you for.
Because Polaris availability on this specific routing fluctuates sharply with corporate travel cycles and Icelandic tourism surges, setting automated fare alerts calibrated to your travel window remains the most reliable way to catch the meaningful price drops before they disappear.
