Flybus-style coach, same 45‑minute KEF–Reykjavík run, different logo
Gray Line Airport Express runs a standard airport coach between Keflavík Airport (Terminal 1) and Reykjavík, with a ride time around 45 minutes, mirroring the pattern you see with Flybus and Airport Direct. Buses meet arriving flights into KEF and link into city departures in the other direction, so you’re buying into the familiar Iceland airport shuttle system, just with a different operator name on the side.
Tickets sit in the same price band as Flybus, typically within a few hundred ISK either way depending on promos and hotel drop-off add‑ons, and you can book online in advance or at the airport after landing at KEF. The core offer is simple: shared coach from the airport to a central Reykjavík terminal, with optional connection to smaller shuttle buses that handle specific hotels and guesthouses inside the city.
Gray Line Airport Express schedules are built around real flight times at Keflavík, so late-night and early-morning arrivals into Terminal 1 usually see a matching bus departure within about 30–45 minutes. Coming back to KEF, departures from Reykjavík are timed to get you to the airport roughly 2.5–3 hours before typical transatlantic flights, which lines up with Iceland’s recommendation to reach the terminal at least 2 hours ahead.
Regulars treat Gray Line as a straight alternative to Flybus or Airport Direct and pull up all three timetables side by side, checking which brand has a departure closest to their inbound or outbound flight instead of assuming one company is always quicker. A Reddit guide from 2024 even calls out Gray Line and Airport Direct together as functioning similarly to Flybus on price, flight connection logic, and hotel shuttle patterns, so choice usually comes down to timing and where your accommodation sits on each map.
Practical tip: check your hotel’s pickup and drop-off stop codes before buying a Gray Line Airport Express ticket, then match them to a specific time on the company’s schedule so you don’t end up waiting an extra 30–60 minutes at KEF or in Reykjavík for the next coach or feeder shuttle.
