The Transportation Security Administration looks set to begin airport temperature screening for departing passengers.
It will be phased in at about a dozen airports, according to the Wall St Journal.
It could begin this week, the WSJ says, but it is still unclear which airports it will start at.
People familiar with the plan said details are still under review by White House officials.
It will cost about $20 million to set up.
Although TSA Administrator David Pekoske said no final decision has been made, there have been ongoing discussions regarding the issue for several weeks.
Frontier Airlines is the first US airline to announce it would conduct its own pre-boarding temperature checks on passengers.
It called on the TSA to administer temperature screening for all passengers at US airports, which has been backed by other carriers including Southwest Airlines.
National flag carriers including Air France, Singapore Airlines and Air Canada have also started conducting mandatory temperature screening for their passengers.
