They're thinking this could go on another 4 or 5 days, but nobody can predict.
Quantas have suspended all flights to Europe too.
This has a knock-on effect, it's not just holiday makers who will suffer. We import a lot of veggies from Africa which have short shelf lives and are sitting there , probably now deteriorating. We'll find shortages in the shops soon of certain items, not to mention the waste of food!
Also important human organs are transported by air, so any medical emergency will become a serious situation!
Just shows how much we're so used to modern technology. The people who directly live under the flight paths, however, are the ones feeling happy at the moment, after a plane going over every 90 seconds they are enjoying the peace and quiet and can actually hear the birds again!
