--Despite an expected plummet in the value of Qantas Airways shares today, institutional investors have backed the airline's management after a dramatic turn in its industrial dispute on the weekend. Qantas opted to ground its entire international and domestic fleet on Saturday, a move which has cost the carrier A$110 million so far. "Every day for Qantas is a fight for survival. The last thing a company that is so exposed to macro influences out of their control wants is an internal battle," Matt Williams from wealth manager Perpetual said. Page B1.
