The airlines updated their policies on Tuesday (19 April) after a Florida federal judge ruled the mask mandate was unlawful on aircraft, trains, buses and other public transportation.
In a statement posted to its website, Virgin Atlantic said: "Effective immediately (Tuesday 19 April), face masks will be a personal choice for our customers and people travelling in either direction between the UK and the United States.
"This aligns with our existing mask policy on routes where international regulations around mask-wearing do not apply, such as between the UK and the Caribbean."
Customers may still be asked to wear a mask when boarding or disembarking flights, according to the regulations of the departure or arrival airport or destination country.
BA also confirmed on its website that facemasks are no longer required for passengers flying to and from the US.
