South Korea Requiring Masks on All Public Transit and Airplanes

This week if you plan to use mass transit or airplanes in South Korea you better bring a mask:

Starting Tuesday, people without a face mask will be barred from taking a bus, taxi or subway train, in a nationwide measure to prevent the spread of coronavirus through public transport.

The measure will be extended to airline passengers ― domestic and international lines ― from Wednesday. 

Operators of these services will be entitled to ban people not wearing a mask. To make sure the system works, the government will not penalize operators based on complaints from people who are refused permission to board.
