I wouldnt think the same applies here...neither XJ or 9L were in bankruptcy, and both have airframes (I.e. 900 and Q400) that are desirable right now to mainline, so both were technically in a somewhat stable longterm situations. Delta sold XJ to Corp without any choice in the matter, considering OO wanted to purchase XJ... same with Compass...F9 had a option to be bought by SWA...Not to mention two different unions...I don't see any similarities
