Iberia Airlines allows passengers to check in online starting 24 hours before the scheduled departure of their flight. Online check-in closes one hour before the flight departs, though in some locations, the cut-off time may vary, such as Lagos and San José where it closes 90 minutes prior, and Caracas where it closes 180 minutes before departure. Passengers need their booking reference or Iberia Plus number along with their last name to complete online check-in. After checking in, travelers can select or change their seat, add baggage, and receive their boarding pass electronically via email, the Iberia app, or through their booking confirmation. If a printed boarding pass is preferred, passengers can print it at home before arriving at the airport or use self-service kiosks or bag drop desks at the airport. For those who prefer or require airport check-in, Iberia recommends arriving at the airport at least three hours before long-haul flights and two hours before short-haul flights. Check-in desks at the airport usually open three hours before the flight and close 60 minutes prior to departure. It is crucial that passengers complete the check-in process and drop off any checked baggage at least 60 minutes before the flight’s scheduled departure time to avoid being denied boarding. Arriving early is important to avoid delays, especially during busy travel periods, as lines at check-in and baggage drop can be long. The timing for check-in ensures enough time for security checks and boarding. Passengers traveling with special requirements or additional services should allow extra time. For families traveling with young children or passengers needing assistance, arriving early helps make the process smoother. In case of group travel, it is also advised to check in early to ensure seats together and avoid complications. Online check-in offers convenience by allowing passengers to skip long queues at the airport, save time, and prepare boarding passes in advance. It is particularly useful for travelers with carry-on luggage only, as they can proceed directly to security and boarding. However, if baggage needs to be checked, passengers must still go to the airport bag drop desk within the designated check-in period. Some airports may have self-service kiosks where passengers can print boarding passes or tag their bags, speeding up the process further. Iberia’s policy aims to provide flexibility and efficiency through online check-in while maintaining the necessary timeframes to ensure all passengers are ready for departure. Passengers should always check specific airport requirements and cut-off times as these can vary depending on destination and airport facilities. In summary, passengers can check in online from 24 hours up to one hour before the flight, and airport check-in desks open three hours prior and close 60 minutes before departure. Following these guidelines helps ensure a smooth journey without unexpected delays or missed flights.
