Bradley International doesn't often get credit as a gateway to the North Atlantic, but for those chasing the midnight sun in business class, it's a surprisingly efficient launch point. There's no nonstop service on this route, so the real strategy lies in choosing your connection wisely: business class from Hartford to Reykjavík typically routes through Boston or JFK on Delta, Newark on United, or increasingly through Icelandair's own network via a domestic codeshare into Boston. The flight time to Keflavík itself is a brisk 5.5 hours once airborne, making this one of the more civilized transatlantic hops — short enough to skip the overnight red-eye grogginess, long enough to actually enjoy a proper lie-flat seat and a glass of something Icelandic.
Having routed through this corridor more times than I can count, I'd steer discerning travelers toward Icelandair's Saga Class when schedules align — it's not a flashy suite product like Qatar's QSuite, but the seat comfort and personal service on the 757 and 767 fleet feel refreshingly intimate for a flight this length. If your connection funnels through JFK, Delta's One Suite on select transatlantic widebodies is worth angling for, particularly on the seasonal summer schedules when Delta ramps up premium capacity to Iceland-adjacent European hubs. United flyers connecting via Newark should check aircraft type carefully, since Polaris seating varies significantly between the 767 and 777 fleets — the 777's reverse herringbone configuration is the one to request. My insider tip: book connections with at least 90 minutes at your US gateway, since Icelandair's KEF operations run remarkably tight, and Keflavík's arrivals hall clears quickly even during peak Northern Lights season in shoulder months.
Summer remains the sweet spot for availability and weather reliability, with May through September offering the most consistent premium cabin space and the added bonus of nearly endless daylight for Reykjavík sightseeing on arrival day. Because premium fares on this route fluctuate with surprising volatility depending on connection routing and seasonal demand, setting up automated fare alerts is genuinely the smartest way to catch business class pricing before it shifts.
