V Australia, Virgin Blue's international carrier, and Virgin America have signed an agreement allowing passengers on both carriers to buy tickets for flights in the USA and Australia on its website or through travel agents.
The interline partnership allows V Australia's passengers to connect to and from Virgin America destinations, which include Seattle, San Francisco, New York, Boston and Washington DC, Virgin Blue says in a statement.
"We are delighted to be formally partnering with Virgin America to offer great travel benefits not only from Australia to the US on V Australia, but beyond Los Angeles across Virgin America's extensive and expanding route network," says Virgin Blue chief executive Brett Godfrey.
"We may be newcomers to our respective markets but we're keen to inspire an industry revolution to benefit travellers and invigorate trans-Pacific travel."
V Australia began operations in February and offers direct flights from Brisbane and Sydney to Los Angeles. Direct Melbourne-Los Angeles flights are scheduled to begin in September subject to regulatory approval.
