Given the current price of fuel and the extent to which major airlines are already cutting back, (UAL and AA for example), with the likelihood that many, many smaller ones will follow, I would be holding on to my job with an established major that is still making a profit like grim death. A move now makes anyone the most junior in their new airline and therefore the most likely to be laid off or even have their job offer revoked after they have given notice to SIA. A good time to consolidate, try to look on the bright side and wait for the storm to pass, then move if you feel you really have to.
