Arriving at Reykjavik (KEF) FAQs

If you're planning scenic drives in September, reserve a 4x4 or all-wheel-drive vehicle for flexible exploration.
Renting a car at Keflavík International Airport (KEF) is recommended if you plan to explore beyond Reykjavík, such as the Golden Circle, South Coast, or Westfjords, especially in September when daylight hours are still sufficient for sightseeing. Book in advance and choose a car suited to changing weather — consider AWD for wet roads; confirm insurance options and gravel protection. If you prefer guided tours, many local operators offer day trips from Reykjavík with airport transfers.
September marks the start of aurora season in Iceland, and after landing at Keflavík International Airport (KEF), you have a reasonable chance of seeing the Northern Lights on clear nights, particularly later in the month.

Use 'Icelandair ORD KEF September' or 'United ORD KEF via London' in fare searches and read recent passenger reviews for service expectations.
