Airlines are also communicating their cleaning processes much more clearly to customers, sending out announcements detailing 19-point (Delta), 30-point (American) and other cleaning checklists.

Turkish Airlines’ coronavirus advisement goes even further, detailing health screening procedures including medical examinations for flight crew, the installation of 11 border crossing health checkpoints at Istanbul Airport, and the presence of thermal cameras to detect fever. Speaking of thermal cameras, they are a frequent presence in many international airports including Singapore, but are not yet common in the US.
