Australian airline Virgin Australia Holdings Ltd on February 11, 2016, said it swung to a half-year profit as it cut costs and attracted more big-spending corporate passengers, while it forecast a return to profitability for the full year. The airline, which competes domestically with Qantas Airways Ltd, posted a net profit of A$45.7 million ($32.4 million) for the six months to December 31, up from a net loss of A$53.1 million in the prior first half.
