Keflavík International Airport (KEF) isn't in Reykjavík. That's the first thing you have to wrap your head around when you’re staring at a 6:00 AM flight departure. It’s actually about 45 minutes away in the middle of a moss-covered lava field. If you’ve spent the last week driving the Ring Road, you’re probably exhausted, your boots are muddy, and the last thing you want to deal with is a logistics nightmare at 3:30 AM.
Honestly, figuring out how to get to airport early morning in Iceland is the one part of the trip people consistently mess up. They assume there’s a 24-hour subway. There isn't. They think they can just "hail a cab" on a Tuesday morning in a blizzard. You can't.
Iceland is expensive, windy, and occasionally unpredictable. When the 4:00 AM alarm goes off in your guesthouse, you need a plan that actually works.
The Reality of the Flybus and Gray Line
Most people end up on the Flybus. It’s the default. Operated by Reykjavik Excursions, these big coaches are timed specifically to meet departing flights. If you're staying at a major hotel, they’ll pick you up at a designated "Bus Stop" nearby.
But here is the catch.
If your flight is at 7:00 AM, the bus company is going to tell you to be at your pickup point by 3:30 or 4:00 AM. You’ll sit in the dark, likely in the rain, waiting for a smaller shuttle to ferry you to the main terminal at BSI. Then you transfer to the big bus. It’s a process. It works, but it feels like a chore when you've only had three hours of sleep. Gray Line offers a similar service (Airport Direct), usually departing from the Reykjavik Terminal at Skógarhlíð. Both are reliable, but neither is "fast." You’re on their schedule, not yours.
Driving Yourself via a Rental Drop-off
If you have a rental car, you might think you've solved the "how to get to airport early morning in Iceland" puzzle. Not quite.

Most rental agencies are located in a cluster about a 5-minute shuttle ride away from the actual terminal. If you’re dropping off a car at 4:30 AM, you have to factor in the inspection time and the shuttle frequency. Some budget agencies like Blue Car Rental or Lotus have streamlined "key drop" boxes, but if you’re using a smaller, off-site company, you might be waiting in the cold for a van to take you to the departures hall.
Check your rental agreement. Seriously. Some agencies charge a "late-night/early-morning" fee just to have a human there to take your keys. If you want to avoid the stress, drop the car off the night before and stay at one of the airport hotels.
The "Airport Hotel" Strategy (The Stress-Free Option)
There are really only two hotels within genuine walking distance of the terminal: the Aurora Hotel and the Courtyard by Marriott (though the Marriott is a long, windy walk). Staying at the Aurora is the ultimate "cheat code" for an early flight. You wake up at 5:00 AM, eat a quick breakfast, and walk 200 meters to the check-in desk.
It’s pricier than a hostel in downtown Reykjavík, sure. But when you calculate the cost of a Flybus ticket for two people (roughly 7,000 to 10,000 ISK total) plus the value of two extra hours of sleep, the math starts to make sense.
Taxis are for the Brave and the Wealthy
Taxis in Iceland are legendary for their price tags. A one-way trip from downtown Reykjavík to KEF at 4:00 AM will easily run you 18,000 to 25,000 ISK. That’s nearly $180 USD for a 45-minute drive.
If you’re traveling in a group of four, it actually becomes competitive with the price of four individual bus tickets. Hreyfill and BSR are the two main companies. You can use their apps to pre-book, which I highly recommend. Don't count on "just finding one" on the street in the early hours unless you're standing right outside the Hilton or the Edition.

Strætó: The Public Bus (Don't Do This)
Iceland has a public bus system called Strætó. Route 55 goes to the airport. It is significantly cheaper than the Flybus.
However, for an early morning departure, it's basically useless. The schedule is designed for commuters and locals, not for the 6:00 AM wave of international tourists. Don't try to save 3,000 ISK by risking your $800 flight. Just don't.
Weather is the Ultimate Deciding Factor
In October 2023, a massive windstorm shut down the main road (Route 41) between the city and the airport. People missed flights. Some spent the night in the terminal.
When you’re planning how to get to airport early morning in Iceland, you have to check Vedur.is and Road.is. If the road is "Yellow" or "Orange" on the map, the buses might be delayed or cancelled. If you see "Red," you aren't going anywhere. In the winter, give yourself an extra hour of buffer time. If you think you need to leave at 4:00 AM, leave at 3:00 AM.
The Check-in Chaos at KEF
Keflavík is a weird airport. It’s quiet at 3:00 AM and then, suddenly, at 4:30 AM, three thousand people arrive simultaneously. The self-service kiosks are your best friend. Tag your own bags, drop them on the belt, and head to security.
Security is usually efficient, but the line can look intimidating. Don't panic. It moves faster than TSA in the States. The real bottleneck is often the tax-refund desk. if you’re hoping to get your VAT back on that 80,000 ISK wool sweater, you need to arrive even earlier. That desk has a mind of its own regarding opening hours and line lengths.

Practical Steps for a Smooth Departure
First, book your Flybus or Airport Direct ticket at least 24 hours in advance. You don't want to be fumbling with a credit card on a mobile site while the bus is pulling away.
Second, if you're staying in an Airbnb, verify your "Bus Stop" number. The city of Reykjavík bans large coaches from the narrow downtown streets, so you have to walk to a numbered pole. Use the busstop.is map to find yours. Some of them are just a pole on a corner; don't expect a heated waiting room.
Third, pack your coat at the very top of your suitcase. You’ll be warm in your hotel, but the transition from the shuttle to the terminal can be brutal if the North Atlantic wind is whipping across the tarmac.
Lastly, check your flight status before you leave the hotel. If there’s a delay due to weather, it’s better to know while you’re still near a coffee pot than while you're standing in a lava field.
To sum it up:
- Flybus for solo travelers or couples on a budget.
- Airport Hotel (Aurora) for maximum sleep and zero stress.
- Taxi for groups of 3-4 who want door-to-door service.
- Rental Drop-off only if you've confirmed the early-morning shuttle logistics with the agency.
The road to KEF is a straight shot, but it’s a lonely one at 4:00 AM. Plan ahead, watch the weather, and keep your boarding pass handy. You've got this.
