Please understand that doing RHS ULH for 7 years and raising small kids in the sandbox while being a remote dad is not the top choice for many.
That is a fair point which is why I brought up the question of what the OP wishes to do with his life. If he wishes to fly a WB then get out there and do it. WB DEC as a NB Capt is a possibility but is is by far the exception and there is a big question mark over whether EK will do it in the future - maybe, maybe not.....certainly far more of a gamble than the upgrade course availability you mentioned.. Probably be opportunities with QR but, yeah, refer to my previous post.
