Pittsburgh to Reykjavik Keflavik Flights (PIT to KEF)

Direct flights from Pittsburgh to Iceland are seasonal. Icelandair flies nonstop between Pittsburgh International (PIT) and Keflavik (KEF), the international airport for Reykjavik, in the warmer months only: in 2026 the route returned in early May and ran until mid-October, with up to four flights a week. The flight takes about 5.5 hours eastbound and about 6 hours back. From November to spring there is no nonstop, and you connect through a larger US gateway instead. As of November 2026, Icelandair has not published its 2027 Pittsburgh season, so check the airline before you plan a summer trip.

Who flies Pittsburgh to Keflavik

Icelandair launched Pittsburgh in May 2024, extended the season in 2025 and returned for a third season in 2026, starting in May rather than April. The flights use Boeing 737 MAX aircraft, a single-aisle jet with Saga Premium seats at the front and economy behind. Days of the week change by year, so check the current timetable with Icelandair rather than relying on last season's pattern.

The route is not only for Iceland. Icelandair connects Keflavik with cities across Scandinavia, the UK and continental Europe, so Pittsburgh travellers can reach places such as Copenhagen, Amsterdam or Paris with one change in Iceland. Icelandair has also been offering a stopover in Iceland on many of these trips, which lets you spend a few days in the country on the way. Check the Stopover terms on Icelandair's site when you book.

Flying in winter: the one-stop options

When the nonstop is not running, you have two practical choices:

• Connect in the US: fly from Pittsburgh to an East Coast gateway with an Icelandair flight to Keflavik and connect there. Icelandair has an interline agreement with Southwest, which in some cases puts both flights on one booking; check whether it is offered for your dates.
• Connect in Europe: fly to a European hub and continue to Keflavik. This is usually longer, because you fly past Iceland and back.

Leave a generous connection on separate tickets. Our layover guide explains how much time to allow.

Flight time and arrival

Eastbound flights leave Pittsburgh in the evening and arrive in Keflavik early the next morning. With about 5.5 hours in the air, you will get only a few hours of rest, so sleep as early as you can. Hotel rooms in Reykjavik are rarely ready at breakfast time, which is why many travellers head to a geothermal spa or start a day trip straight from the airport.

The return leaves Keflavik in the late afternoon and lands in Pittsburgh in the evening. Iceland does not use daylight-saving time, so it is four hours ahead of Pittsburgh in the US summer and five hours ahead in the US winter.

Pittsburgh International Airport

PIT opened its new landside terminal in November 2025, with check-in, security and baggage claim in one building linked to the existing airside gates. International arrivals clear US customs at PIT on the way home. Arrive at least two to three hours before an international departure, because bag drop for the Icelandair flight closes earlier than for domestic flights.

Keflavik to Reykjavik

Keflavik airport is on the Reykjanes peninsula, about 50 kilometres from Reykjavik. The main options are:

• Airport coaches: Flybus and Airport Direct run to bus terminals in Reykjavik in about 45 minutes, with hotel drop-off add-ons.
• Public bus: Strætó route 55 is cheaper but slower; check where it stops in the city before you rely on it.
• Rental car: the most popular choice for travellers heading out on the Ring Road or the Golden Circle. Desks are at the airport.
• Taxi: available outside arrivals, but expensive for the distance.

Reykjavik's other airport handles domestic and some short regional flights, not transatlantic flights, so make sure your booking says KEF.

Entry rules for US citizens

Iceland is in the Schengen area. US citizens do not need a visa for tourist stays of up to 90 days in any 180-day period across all Schengen countries combined; our guide to the Schengen 90/180 rule explains how the count works. Your passport should be valid for at least three months after the date you plan to leave the Schengen area, and it must have been issued within the last ten years.

The EU's Entry/Exit System (EES) is in operation, so on your first entry you register your face and fingerprints at the border instead of getting a passport stamp. ETIAS, the planned travel authorisation, is not yet in operation: the EU says no application is accepted or needed as of November 2026, and a start date will be announced months ahead. Ignore websites that offer to sell you one. Our EES and ETIAS guide covers both.

Best months to fly

The nonstop runs in Iceland's best travel season. June and July bring near-constant daylight and the easiest road conditions; May and September are quieter, with cooler weather and, in September, the first chance of northern lights. Winter trips through a connection bring short days, northern-lights chances and sometimes difficult driving, so plan for weather delays and check road conditions before every drive.

Baggage and fare types

Icelandair sells economy in several fare types. The lowest may not include a checked bag or seat choice, while higher fares add a bag and more flexibility. Iceland trips often need bulky layers, hiking boots and rain gear, so check the allowance before you choose the cheapest fare. If you connect from a US domestic flight on a separate ticket, the two airlines' bag rules may differ. Our guide to airline baggage rules explains what to look for.
