Frontier Airlines implemented new safety guidelines for all passengers by requiring temperature checks before customers board their flight, according to the company.
The new measures come as cities across the nation lift travel restrictions initially put in place to prevent the spread of COVID-19.
As of Monday, any passenger or crew member with a temperature of 100.4 degrees Fahrenheit or higher will be denied boarding as a step to better protect others while flying, company officials said.
In April, Frontier officials announced passengers and crew members would be required to wear face coverings that must be also worn by all passengers and team members.
