OREANDA-NEWS. TAM Airlines and US Airways today completed their transition to oneworld - marking the biggest single-day expansion of the world's leading quality airline alliance since its launch 15 years ago.

Both newcomers started offering oneworld's services and benefits from their first flights this morning, on leaving the Star alliance after their final departures yesterday.

The landmark addition of these airlines to oneworld is being celebrated at a ceremony today at TAM's Sao Paulo hub, attended by the CEOs of the alliance's established member airlines, during which TAM will show off the first of its aircraft painted in the oneworld livery.

TAM and US Airways significantly expand oneworld on many key measures:

Increasing the number of passengers carried annually across the alliance network by a third, adding another 120 million customers a year.

Expanding the annual capacity offered by the alliance by 20 per cent.

Adding almost a hundred destinations to the oneworld network - a near 10 per cent increase.
