Dominykas Narbutas, acting head of communications at the ministry, said people could be flown home by planes chartered by the government or one-off commercial flights.
"Several options are being considered, but there is no concrete decision yet," he told BNS.
Narbutas told LRT Radio that travelers would need to have a negative COVID-19 test result to be allowed to return or get tested at the airport.
Lithuania is still waiting for a joint decision from the European Commission and is also holding consultations with Latvia and Estonia, according to the official.
The government on Sunday imposed a ban on all passenger flights from the UK amid fears about a new strain of coronavirus in the country.
The measure, in effect from 4 a.m. on Monday through December 31, does not affect cargo flights.
