The super printed off the list of names for the whole airline - and 18 is the total leaving across the airlines in the next 3 months. I think it will be 100 leaving over a year but this is less than 5%. People do care and that is why they give data on this forum.
There is also lots of interesting audited data on the SEC 20f which is located here:-
