Iceland has become one of the easier long-haul international trips to book from the US, thanks to strong nonstop service and a genuinely useful stopover option most travelers don't know to ask for.
The airport
Keflavík International Airport (KEF), about 45 minutes from Reykjavik, is Iceland's only major international gateway and the arrival point for essentially every visitor.
Getting there from the US
Iceland's flag carrier and other carriers serving the route offer nonstop flights from a number of US East Coast cities (Boston, New York, Washington DC area, and others), with somewhat fewer nonstop options from further west. Because Iceland sits roughly midway between North America and mainland Europe, it's also a common and often cost-effective stopover on the way to other European destinations.
The stopover option
Some airlines flying this route let you add a multi-day stopover in Iceland at no extra airfare if you're continuing on to mainland Europe — worth asking about specifically if your trip includes both, since it can turn one flight into two destinations for close to the same price.
When to go and when to book
Summer (June–August) is peak season for long daylight hours and hiking, while winter (roughly October–March) draws visitors for the Northern Lights — both stretches see higher demand and fares than the shoulder months. Book roughly 2–4 months ahead for either peak window; Iceland's relatively short flight time from the US East Coast means you generally don't need to book as far out as other long-haul international trips.
What to check before booking
- Whether your fare includes checked baggage — some carriers serving this route price baggage separately as an add-on, so compare the full cost, not just the base fare.
- Car rental plans — many visitors rent a car to see the Ring Road or Golden Circle; confirm you can pick up near Keflavík if you're not overnighting in Reykjavik first.
- Season-specific gear and daylight hours, which affect how much you can realistically see per day depending on when you visit.
