I actually thought attrition would likely handle the temporary excess without requiring furloughs as the senior FOs and junior CAs jumped ship, but the failure of Boeing to get the MAX 7 & 10 certified has certainly slowed hiring at SWA and Delta, and if UA doesn't cut the rumored deal with Airbus, they may soon cut back hiring as well,so attrition may taper off for awhile - which is perhaps very unfortunate for the junior FOs and the junior CAs that may be most affected. Those FOs who do have 1000 hr of 121 time (most of them) might be able to ride out a downturn as a regional DEC - no shortage of openings there - which would help them through a furlough economically but it'd be a real QOL hit.
