And of course if this reduces the amount of overall air travel it would also reduce the number of air crews that would require exemption. The way I read it, even folks who have an exemption from quarantine (far longer list than the exemption to the PCR test) will still need to comply with this rule, which will probably reduce the number of people asking for exemptions too given that some essential travel perhaps will also get curtailed with more difficult rules.

Will be interesting to see if this leads to more flight cancellations, particularly to sun destinations, or if people are willing to go this extra step to continue to travel.
