US domestic airlines and civilian pilots will be allowed to fly into Kabul to conduct evacuation or relief flights, the US Federal Aviation Administration (FAA) has said.
They would need prior approval from the US Defense Department though.
Currently, they are prohibited from flying through Afghanistan airspace or into Kabul airport without permission.
A Pentagon spokesman told reporters earlier this week that the US military had assumed air traffic control at Kabul airport.
It's not clear, however, when the US will seek to use its domestic carriers for evacuation efforts.
The United States has evacuated 6,000 people since 14 August, according to the White House.
