Lithuania's Kaunas airport said it has concluded negotiations with Ryanair to begin flying to the Baltic state.
"The negotiations are finished, but all the details are to be announced by representatives of the Irish company," Kestutis Cucenas, head of Kaunas airport said.
"Representatives of Ryanair will hold a briefing in Kaunas on Tuesday," he added.
In February, the Baltic state in February sent letters to eight low-cost European airlines inviting them to begin service to the Baltic state but only received a reply from Ryanair.
Ryanair had expressed interest earlier in serving the Baltic state and had been in talks with Lithuanian officials, but those talks had failed.
The transport ministry earlier said that it was ready to provide the necessary infrastructure for Kaunas airport and would organise public transport from Vilnius to the second-largest city, some 100 kilometres away.
Kaunas airport to date mainly served cargo flights.
