One pilot shared this link with me https://simpleflying.com/royal-brunei-a ... freighter/ the headline of which is "Royal Brunei Converts An A320neo". On digging into it, following the links and reading carefully I believe this was not a full freighter conversion, which involves new cargo doors, reinforced floors with systems for moving cargo and removing all the windows, but a "Preighter" conversion where passenger aircraft have there seats removed so cargo can be put into the passenger compartment. Here is an image:
In the era of Covid some airlines have even carried cargo in the main compartment without removing the seats as can be seen here:

The question is should we at FSA do something to support this?
