Aeroflot is to operate a new daily service between Dublin and Moscow with an Airbus A320 aircraft.
The daily service will start from October 28 and Dublin Airport has welcomed the announcement.
"We are delighted to welcome Aeroflot back to Dublin Airport with this direct connection to Moscow," Vincent Harrison, Dublin Airport Managing Director, said. "The new service will further boost trade and tourism between Ireland and Russia."
"About 42,000 passengers travelled between Dublin and Moscow last year on indirect flights so I have no doubt this new direct route will be very popular in both directions," Mr Harrison said.
Vitaly Saveliev, Chief Executive of Aeroflot, said Aeroflot continues to expand its international route network.
"We are pleased to offer travellers new international destinations as well as additional flights to popular tourist destinations, thus expanding travel options with Aeroflot for both business and leisure travellers."
From October to March of next year, flights will depart Moscow Sheremetyevo at 19.20 and arrive in Dublin at 20.45. The return flight will depart Dublin at 21.45 and arrive in Moscow Sheremetyevo at 05.00.
Aeroflot previously operated a Dublin to Moscow service between 1987 and 2003. The airline is Russia's flagship carrier serving 146 destinations in 52 countries.
So far this year, more than 21.2 million passengers have travelled through Dublin Airport, which is a 6% increase over the same period last year. More than 1.2 million additional passengers have been welcomed during the first seven months of the year.
