Billionaire Lucio Tan said he plans to return his group’s Philippine Airlines to profit before selling a stake, two weeks after the carrier’s president said talks with a strategic investor were likely to produce a deal by the end of this year.PAL Holdings, the carrier’s parent, booked a net loss of 501 million pesos (9.8 million dollars) in the second quarter after reporting a 1.13 billion peso deficit in the previous quarter as higher fuel costs and aircraft lease charges boosted expenses.
