I forgot to take an additional medical face mask and the one I am wearing is wet. What should I do?
Passengers should ensure sufficient supply of medical face masks for the duration of their journey. Airlines may carry a number of medical face masks on board, especially for long-haul flights where the need to change masks may be advised by public health authorities. However you should not rely on airlines to supply you with face masks, as the number of face masks carried by the airline might be limited.
