What the ex-SAA guys and girls need to know is that CX recruitment will lie to them to get them in.
No matter what they are told there can be:
1) No DECs (every COS in CX only allows promotion iaw seniority),
2) No JNB basing (a hell of a lot of guys senior to you have wanted that for decades),
3) Any "commuting roster" will be around 21 days in length and involve travelling to West-coast of USA and back (ie. massively fatiguing).
They really need to understand that.
