Virgin flies into the unknown with growth plan VIRGIN Australia looks set to keep the market guessing on its capacity growth plans for the second half of the financial year as new data released yesterday confirmed that its yields between July and November had been positive despite lower passenger numbers. Virgin has maintained guidance of a 3-4 per cent increase in capacity in the first half and is tracking at about 3.5 per cent, but has declined to give a forecast for the second half. It is understood it has no plans to give further guidance at its half-year results next month.
