Davies, who is currently the airline's Digital marketing head, will be responsible for all parts of the BBC website outside of the UK, including news, weather, business, technology, lifestyle and the recently-launched travel section.
He will report directly to BBC.com's executive vice president and managing director Luke Bradley-Jones.
Davies's appointment comes as Worldwide prepares to drive forward the launch of an international version of catch-up service BBC iPlayer.
At last month's Edinburgh TV Festival, BBC director general Mark Thompson pledged that the corporation would make a commercial version of iPlayer available to overseas users within a year.
Towards that aim, Worldwide has promoted BBC executive Mark Smith to become the new global iPlayer launch director with a direct remit to oversee the rollout.
