Route Intelligence
Business Class from Greenville to Reykjavik
Business class flights from Greenville to Reykjavik run $2,150–$5,750 round-trip through BestBusinessClass.com, a savings of roughly 35-55% off the retail fares airlines publish directly for this connecting itinerary. Since GSP has no widebody service to Iceland, every Greenville to Reykjavik business class routing connects through a domestic hub — Dallas, Charlotte, Atlanta, Minneapolis, Houston, or Chicago — before picking up the transatlantic widebody leg. That connection is actually useful: it lets you choose between American, Delta, and United's long-haul products rather than being stuck with whatever single carrier serves your home airport, and it typically only adds an hour or two to total travel time versus a nonstop from a larger city.
Airlines & Cabin Experience
All three major carriers put real business class hardware on the Iceland run once you're on the widebody leg. American's Flagship Business gives you a 1-2-1 lie-flat suite with Casper bedding and access to Flagship Lounges at the connecting hub — Charlotte or Dallas being the strongest options here. Delta's Delta One Suite is the standout for privacy seekers, with a closing door at every seat and Tumi amenity kits, and Atlanta or Minneapolis connections put you right in Delta's home turf for lounge access. United's Polaris product rounds things out with lie-flat pods in the same 1-2-1 layout, Saks Fifth Avenue bedding, and Polaris lounge access through Chicago or Houston. None of these are bad choices for a roughly 7-hour transatlantic segment — the real decision usually comes down to which connecting hub works best with your Greenville schedule and which loyalty program you're already invested in.
Pricing & Best Time to Fly
Pricing on Greenville to Reykjavik business class follows a clear seasonal pattern. January, February, and March are the cheapest months to fly, largely because Iceland's tourist crush hasn't started and airlines discount business class inventory to fill seats — this is also prime time for chasing the northern lights, so the low fares align nicely with peak sightseeing. October and November offer a similar shoulder-season discount, with fewer crowds and softer pricing before the winter holiday surge. Booking 3-4 months ahead during these windows typically nets fares in the lower half of our $2,150–$5,750 range; waiting until inside 30 days almost always pushes you toward the top end or into sold-out business cabins, since these are relatively small widebody aircraft on the Iceland route.
Why Book Through BestBusinessClass.com
Because this is an eastbound overnight flight, the transatlantic leg usually departs the US hub in the evening and lands in Reykjavik the next morning — meaning the lie-flat seat is doing real work. A few hours of decent sleep on a fully flat bed makes a genuine difference when you land and want to start exploring the Blue Lagoon, the Golden Circle, or downtown Reykjavik on your first day rather than crashing in a hotel room. Reykjavik itself draws travelers for its geothermal spas, glacier and volcano tours, and the northern lights in winter, plus its usefulness as a stopover hub if you're continuing on to mainland Europe — Icelandair's home turf makes onward connections easy.
