KLM is cautiously restarting flights to a number of its European destinations. From Tuesday, the airline will perform daily flights to Barcelona, Madrid, Rome, Milan, Budapest, Prague, Warsaw and Helsinki. Travelers will be obliged to wear masks that cover their nose and mouth, the airline announced.
"This involves face protection in the broadest sense of the word," a spokesperson for KLM said to broadcaster NOS. "A scarf is also fine if it is tight." Though masks are preferable to other forms of face covering.
