To Go back on thread:
Cargo ops will survive and especially the long haul wide body cargo operators as I guess long haul pax will be affected for some time to come reducing the overall cargo capacity.
There lies the crux: the longer the aviation market is down the better it is for the cargo operators. Once the airlines fly their usual schedules the cargo ops will be hit hard given the total market is most likely still below 2018/19 levels.
