To check in online KLM airlines, first of all open KLM’s website or the KLM app -online check in usually opens 30 hours before scheduled departure (24 hours for flights to/from the United States). Knowing the KLM online check in time first you have to  pick seats, add baggage or buy upgrades ahead of the airport rush. If you are travelling on routes that have special rules, the close/open  window for this can differ, so always confirm your booking before you  try to check in.

Steps for this are given below-

Step 1- retrieve your booking and start the process.

Go to KLM.com -check in or open the KLM app, then you have to enter your booking preferences(PNR) and last name to check in online KLM airlines. Because the klm online check in time opens in the 30-hour/24-hour windows, you have to log in during that period to avoid “not yet available” messages. You can also log in with your Flying Blue account or scan the email KLM sends the reminder you to check in.

Step 2-confirm passengers and travel documents.

After you retrieve the reservation ,you have to confirm each passenger’s details and enter passport or ID data if required for you to check in online KLM airlines; this is often mandatory. Now watch the KLM online check in time prompts-some of the destinations ask for extra document checks and might hold boarding passes until verification at the airport. Choose seats, declare or pay for checked baggage, and save your boarding pass to your phone or make a print out of it.

Step 3-boarding pass and baggage drop.

Once the system issues your boarding pass then you have successfully checked in online KLM airlines; if you travel with hand luggage only  then you can directly go to security. If you have checked luggage, you have to  note the KLM online check in time information for bag drop: KLM’s drop off typically closes around 40 minutes before European departures  and 60 minutes for intercontinental flights -that has arrived early to avoid missing the drop off window. Use  self-service or the bag drop counter at the airport if available.

Final tips and exceptions .If you miss the KLM online check in time or you need any special assistance, directly head to the airport check in desk- remember boarding that generally starts 60-25 minutes before the departure, so plan accordingly.
