If you are asking, “Why can’t I check in on Icelandair?”, the problem is often caused by timing, incorrect booking details, a technical issue, or a requirement that means you need to complete check-in at the airport.

Icelandair currently states that online check-in is available 24 hours before departure for all destinations. To start, you normally need your last name and either your booking reference or ticket number.

If your Icelandair online check-in is not working, do not immediately assume that your ticket is invalid. Try the troubleshooting steps below, then use the airport check-in options if the online system still does not work.

When Does Icelandair Online Check-In Open?

Icelandair's online check-in opens 24 hours before your scheduled departure. If you are trying to check in earlier, the system may simply not be available yet.

This is one of the first things to check when Icelandair check-in is unavailable.

For example, if your flight leaves at 6:00 PM tomorrow, online check-in should become available around 6:00 PM today.

What You Need for Online Check-In

Icelandair's check-in page asks for:

  • Your last name

  • Your booking reference or ticket number

The airline gives examples of booking references and ticket numbers on its check-in page.

Make sure the information you enter matches your reservation.

Why Can’t I Check In on Icelandair?

There are several possible reasons your Icelandair flight check-in may not work.

1. Check-In Has Not Opened Yet

The most common explanation is that you are attempting to check in more than 24 hours before departure.

Icelandair says online check-in is available 24 hours before departure for all destinations.

What to do: Wait until the 24-hour check-in window opens and try again.

2. Your Booking Reference Was Entered Incorrectly

A small typing mistake can prevent the reservation from being located.

Check that:

  • Your booking reference is correct.

  • Your last name is entered correctly.

  • You have not accidentally added spaces or characters.

  • You are using the Icelandair booking reference rather than a reference from another travel website.

If you booked through a travel agency or another booking service, check your confirmation email for the airline's booking details.

3. You Are Using the Wrong Passenger Information

The check-in system uses your reservation information to find your flight. If the surname does not match the booking, the system may not retrieve the reservation.

Try entering the surname exactly as it appears on your booking confirmation.

If you recently changed your name or your reservation contains a spelling issue, contacting Icelandair or your booking provider may be necessary.

4. The Website or App Is Experiencing a Technical Problem

Sometimes Icelandair online check-in not working is simply a temporary technical issue.

You can try:

  1. Refreshing the check-in page.

  2. Closing and reopening your browser.

  3. Using a different browser.

  4. Trying a private/incognito browser window.

  5. Switching between Wi-Fi and mobile data.

  6. Updating or restarting the Icelandair mobile app.

  7. Trying again after a short period.

Icelandair also provides check-in through its mobile app, where passengers can check in and access their boarding pass.

5. Your Booking May Require Airport Assistance

Not every check-in situation can necessarily be completed entirely online.

If the website does not allow you to complete the process or issue a boarding pass, the practical solution is to use the airport check-in desk or an available self-service kiosk.

Icelandair lists airport counter check-in and self-service check-in as alternatives to online check-in.

6. Your Flight Details May Have Changed

If there has been a schedule change or another change affecting your reservation, the online check-in process may not behave as expected.

Check your flight information before repeatedly attempting check-in. Icelandair provides a flight-status tool for checking current flight information.

If your itinerary has changed, follow the instructions provided by Icelandair or contact the airline if the reservation needs attention.

7. Your Reservation May Not Be Properly Ticketed

A reservation and a completed ticket are not necessarily the same thing. If there is an unresolved payment or ticketing issue, check-in may not proceed normally.

Review your booking confirmation and payment information. If you are unsure whether your ticket has been issued, contact Icelandair or the travel agency that made the booking.

How to Fix an Icelandair Check-In Error

If you receive an Icelandair check-in error, work through these steps in order.

Step 1: Confirm the Departure Time

Calculate whether you are actually inside the 24-hour online check-in window.

If not, there is nothing to fix yet. Try again once check-in opens.

Step 2: Recheck Your Booking Information

Enter your:

  • Last name

  • Booking reference or ticket number

Carefully compare the information with your booking confirmation.

Step 3: Try the Icelandair Website Again

A temporary browser problem can sometimes cause the check-in page to fail.

Try another browser or device and make sure your internet connection is stable.

Step 4: Try the Icelandair App

Icelandair's mobile app supports check-in and allows passengers to download their boarding pass.

If the website is giving you trouble, the app can be a useful alternative.

Step 5: Check Your Flight Status

Look up your flight before heading to the airport. This helps confirm that the flight information in your booking is still current.

Step 6: Use Airport Check-In

If online check-in continues to fail, do not keep trying indefinitely as your departure time approaches.

Icelandair offers airport check-in options, including staffed counters and self-service facilities at certain airports.

Bring your passport or other required travel documents and your booking information.

What If I Can't Get My Icelandair Boarding Pass?

Completing online check-in and receiving a boarding pass are normally connected, but a technical or document-related issue can prevent the boarding pass from being generated.

Icelandair says passengers who complete online check-in can receive their Icelandair boarding pass by email, download and print it, or add it to Apple Wallet or Google Wallet.

If you cannot obtain the digital boarding pass, use the airport check-in process. The important thing is to resolve the issue before the applicable airport and boarding deadlines.

Can I Check In at the Icelandair Airport Counter?

Yes. Icelandair lists airport-counter check-in as an alternative to online check-in.

If Icelandair online check-in fails, arriving at the airport with enough time for check-in, baggage, security and any document checks is the safest approach.

Do not wait until the last few minutes before departure to solve an unresolved check-in problem.

Can I Use an Icelandair Self-Service Kiosk?

Icelandair provides self-service check-in facilities at certain airports. Its online check-in information specifically identifies self-service facilities at Keflavík, Billund and Copenhagen for check-in and baggage processes.

Availability can depend on the airport and your itinerary, so follow the instructions displayed at the airport.

What If I Have Checked Baggage?

If you successfully complete online check-in and have checked baggage, you still need to drop off the baggage.

Icelandair says passengers with checked baggage should go to the check-in desk and show their boarding pass. At Keflavík, Billund and Copenhagen, self-service facilities are available for baggage drop-off, with passengers using a kiosk to check in and print baggage tags.

If you only have permitted carry-on baggage and have completed online check-in, Icelandair says you can proceed toward the gate.

Quick Troubleshooting Checklist

If your Icelandair check in is unavailable, use this quick checklist:

  • Confirm that your flight departs within 24 hours.

  • Verify your last name.

  • Verify your booking reference or ticket number.

  • Check your flight status.

  • If online check-in still fails, check in at the airport.

When Should I Stop Troubleshooting Online?

If your flight is approaching and you still cannot complete check-in, going to the airport is usually more useful than repeatedly refreshing the website.

Bring:

  • Passport or required travel documents

  • Booking confirmation

  • Ticket or booking reference

  • Any required visa or entry documents

  • Your phone with the Icelandair app or booking information, if available

Icelandair's pre-flight information emphasizes having your travel documents ready before departure.
