IMHO, staffing is a function of block hours flown. It's over simplified, but really comes down to that.
You have 'X' #'s of fleets. Each of those fleets fly 'Y' # of block hours.
You are going to need 'A' number of pilots to operate those flights. (The oversimplification is that the block hours account for known absences, vacations, etc.) Then you have to have a reserve buffer of a certain % to ensure completion factor. 7-18%ish depending.
So, what's the cost to furlough a pilot? It depends. What are your training costs? Displacement costs? Severance pay? vs. Keeping the same number of pilots on property till you see a recovery of pre-crisis block hours. Also, what was your staffing model before the crisis? Were you running 'fat' or 'lean' - what was the average pilot flying/crediting? Does your working agreement call for furlough mitigation? What is required?
Management has to look at all of this along with doing their long term planing when deciding to furlough.
What's the break even point after taking into account all the mitigation? Cost of furlough and recall vs. keeping pilots on property.
So, yes, carriers are currently cutting capacity, but they are also looking at forward bookings and trends and I wouldn't trust Seeking Alpha articles for future planning. No one really knows how things are going to play out in the next 365 days, it's a constantly moving picture that has way too many parts to track. We need Hari Seldon figuring this out.
