The White House has confirmed the move, which will see the current rules extended until 18 March.
The measures requiring all passengers, unless medically exempt, to wear a mask on transport including trains, planes, buses, cruise ships and other forms of transportation, plus at public transport hubs, were originally due to expire on 18 January 2022.
But the latest coronavirus variant of concern, omicron, has seen countries around the world re-tighten domestic and travel restrictions.
The TSA first introduced the requirement to wear a mask on public transport in February 2021. The directive has since been extended several times, once from May to September, then from September to January.
