Temperature checks
The Trump administration is preparing to roll out temperature checks conducted by the TSA at some airports. Some airlines are taking passengers' temperatures and airports are using thermal scanning to check crowds.
Health declarations
Dutch carrier KLM asks passengers from high-risk areas to affirm their health before flying. The carrier reserves the right to keep passengers it deems ill off the plane.
Boarding
Air France is boarding the back of the plane first, making business class and other higher fare passengers wait.
On board
China Southern and other carriers are not seating passengers in the middle seat, or spacing them out through the cabin. Xiamen Air keeps the last three rows free for ill passengers.
The lavatory
Ryanair, Europe’s budget carrier, is requiring passengers to raise their hand and seek permission to use the bathroom.
