Russian carrier Transaero Airlines is cancelling the fuel surcharge included in the price of tickets on its international routes.
Savings can be up to £30-40 one-way on the London-Moscow route.
The offer is subject to online purchase on the carrier’s website, sales at the airline’s ticket offices or the airline’s agent offices abroad.
The fuel surcharge depends on the range of flights and specific routes.
The airline’s deputy chief executive for commerce, Roman Vdovenko, said: “We are glad to offer our clients more affordable prices in the run up to the new year holidays.
“We are certain our clients will highly appreciate low airfares on international routes with the guaranteed high level of service.”
