Right now, if you could apply to a cargo carrier, be it whatever airframe, jump at it!
I fly for a cargo carrier, I passed the selection for a biggish low cost carrier and was placed in the hold pool a few months ago. I also attempted Aer Lingus which I did not pass.
The first one has not announced any reduction or cuts that I'm aware of, but IAG made a statement today, those that passed the Aer Lingus selection have had their offer withdrawn and they have already given notice to their current employer.
I am truly blessed to have not been affected by all of this for the time being. Our schedule has changed a bit only to avoid layovers in some cities, but the flying not only is intact, but it may also increase since some passenger carriers that carry cargo in their belly holds are grounded.
The problem is that you will have to compete with lots of experienced pilots on the market right now.
