Russian President Vladimir Putin was also set to visit athletes settling into the Olympic villages as the authorities rushed to make the finishing touches ahead of Friday's opening ceremony in the Fisht Stadium.
Putin has vowed that Russia will ensure hospitable and top class Games for everyone but the $50 billion project has long been overshadowed by Russia's law outlawing "gay propaganda" to minors.
Gay rights group All Out is organising protests in 19 cities around the world -- including Saint Petersburg in Russia but not Sochi itself -- urging sponsors to "break their silence" on the controversial legislation.
"This is the moment to push sponsors to use their economic power to call for an end to these discriminatory laws," it said in a statement.
The international demonstrations by LGBT activists plan to target big-name Olympic sponsors such as McDonald's, Coca-Cola, Samsung, watchmaker Omega and Visa credit cards in cities including London and New York.
In a protest in Melbourne, protesters gathered outside of Flinders Street Railway Station, brandishing pictures with the slogan "Olympic sponsors speak out now!"
US telecoms giant AT&T on Tuesday joined a growing international chorus of disapproval at the "gay propaganda" law, which activists say is vehemently homophobic by definition.
"We stand against Russia's anti-LGBT law," said AT&T, the biggest US cellphone and landline operator, in a blog on its corporate website.
The Olympic flame is due to spend the next three days in and around Sochi, including Friday when it will finally arrive at the stadium to light the Olympic cauldron.
The flame started its journey in Sochi by being taken through the Lazarevsky district north of the centre and later in the afternoon was expected in Rosa Khutor where the mountain events are being held.
The stadium is itself some 40 kilometres south of Sochi city centre and in the next days the flame is expected to be carried by runners, on trains, on sailing boats and even possibly on a Black Sea dolphin.
Flame carriers are set to include UN Secretary General Ban Ki-moon and IOC president Thomas Bach as well as luminaries of Russian sport like pole vault champion Elena Isinbayeva.
Putin to open Russian village
Putin assured International Olympic Committee (IOC) president Bach the day earlier that all guests would feel comfortable at the Games.
"The main task is to make the Sochi Games a celebration for all sport lovers in the world," Putin added.
Putin was later expected to visit the Olympic village where he was to take part in the official welcome for the Russian team.
There has been particular concern that not all accommodation for the media has been ready on time with reporters swapping tales of last-minute repairs and non-existent wi-fi.
Security at the Winter Games has also been a major fear with tens of thousands of members of the Russian security forces on duty to ward off the threat of attacks from militants from the nearby Northern Caucasus.
A top US counter-terrorism official said Tuesday the biggest security threat facing the games was a possible attack in areas outside of Sochi and its heavily-guarded venues.
Matthew Olsen, director of the National Counter-terrorism Center, said the primary threat came from the Caucasus Emirate, which he described as "probably the most prominent terrorist group in Russia".
President Barack Obama has been assured that the United States is "taking all appropriate steps regarding the safety of Americans" at the February 7-23 games, the White House said.
Two Austrian athletes taking part in the Winter Olympics have been threatened with kidnap in an anonymous letter, the country's interior ministry said Tuesday, with local media citing ski star Marlies Schild and Janine Flock as the targets.
There have also been huge concerns about the environmental consequences of the Olympics but Putin on Tuesday had sought to play up the ecological benefits by taking IOC members to meet leopards that Russia wants to re-introduce to the mountains above Sochi.
A six-month old leopard name Grom (Thunder) was flustered by the cameras and attacked two reporters. Putin was then shown stroking the animal on his knee.
