With this 'RUSH' to work from home, they can let the pilots operate the flight deck from home, and the cabin crew can be 'upskilled' to deal with any issues that may occur, on the other hand the upskilling will have to include EFTO, Bomb Threats, diversions, multiple bird strikes, cabin fires, cargo fires, fuel freezing, tea pot failure, depressurisation, battery fires, and the millions of other items than can mess up the day. I think they do well to manage on two crew, prob better to get an extra on in to reduce the workload.
