IATA and ACI put out a press release on the subject of restarting aviation yesterday.
ACI and IATA Outline Roadmap for Aviation Industry Restart
The paper itself is fairly brief and linked to at the end of the press release. All fairly consistent with the QF proposed approach (having regard to the relatively low transmission risk in Australia)
This is what the paper says about social distancing generally
Based on information we have analyzed, the risk of transmission of COVID-19 from one passenger to another passenger on board is very low. Possible
reasons are that customers sit facing forward and not toward each other, seat backs provide a barrier, the use of HEPA filters and the direction of the air flow on board (from ceiling to floor), and the limited movement onboard aircraft once seated add to the onboard protection. As an added protection against possible in-flight transmission, IATA recommends the use of face coverings by travelers in situations where physical distancing cannot be maintained, including in flight. In this
regard, it should not be assumed that physical distancing on board (e.g. through blocked seats) would be necessary.
It also makes these comments about seating inflight
