The restoration of international flying is going to take some time, especially to the US. I cannot even imagine what a recovery looks like domestically after everyone is broke or behind a year in their repayments. Uncharted waters.
On the other hand, its not too farfetched to imagine a return to regulated fares and protectionism. I would be very surprised if any ME carrier ever has more than one or two services a day to Oz. The government is going to have to abandon its free market ideology in order to restore local jobs ( and crucially, the local tax base)
