How Early Can You Check In for a KLM Flight? KLM Royal Dutch Airlines offers multiple check-in options to accommodate travelers, allowing them to check in as early as 30 hours before their flight's scheduled departure time for most destinations. However, for flights to or from the United States, online check-in opens 24 hours prior to departure. It's important to note that online check-in closes 1 hour before departure for all flights. To check in online, visit KLM's official website or use the KLM mobile app. After entering your booking details, you can select or change your seat, add baggage, and receive your boarding pass electronically. This method is convenient and helps you avoid long lines at the airport, especially if you're traveling with carry-on luggage only. If you prefer to check in at the airport, KLM provides self-service kiosks and staffed check-in counters. Self-service kiosks are available from 2 hours before departure for European flights and from 3 hours before departure for intercontinental flights. At the airport counter, check-in is available from 2 hours to 40 minutes before departure for European flights and from 3 hours to 1 hour before departure for intercontinental flights. However, it's advisable to arrive at the airport earlier to allow ample time for security screening and other pre-flight procedures. For passengers eligible for SkyPriority—such as Business and First Class travelers, Flying Blue Gold and Platinum members, and SkyTeam Elite Plus members—check-in is available from 2 hours to 40 minutes before departure for European flights and from 3 hours to 1 hour before departure for intercontinental flights. SkyPriority offers benefits like priority check-in, boarding, and baggage handling, enhancing the travel experience. In summary, KLM allows passengers to check in online starting 30 hours before departure for most flights and 24 hours before departure for flights to or from the United States. Online check-in closes 1 hour before departure. At the airport, check-in times vary depending on the destination and method chosen. It's recommended to check in as early as possible within the allowed time window and arrive at the airport with sufficient time to complete all necessary procedures. |
