I am trying to re- schedule our return flight from SJO (as PTY-AMS) is canceled but I always get this error:
"We are sorry, but selecting these travel dates is not possible due to the change conditions of your ticket type. You can find these conditions in your booking confirmation e-mail. If you would like to change flights due to a flight disruption, special rules may apply, see: KLM.com > Flight info > Flight disruptions. Please select other travel dates, or contact us."
This happens for all travel dates, despite the fact that SJO-AMS is still scheduled
