Alloha, what you say concerning the "Contract Completion" bonus being paid when you are leaving Saudia at the normal end of your contract term was, until recently, correct. It was part of and included in your final settlement, provided you completed the full term of your contract. If you left before your contract completion date, or where terminated before, then the likely hood would be that you would not get the "contract completion bonus" for the obvious reason i.e. you would not have completed your contract term.
Until recently, the "Contract Completion" bonus was being paid to pilots who renewed their contracts. In these cases, it was common for the bonus payment to be delayed for a few months. Seven months delay would have been excessive and unusual.
However, what is happening recently is different. Pilots who are renewing their contracts are being told by both GM Flying and VP Flying that the "Contract Completion" is not going to be paid "until further notice" and "subject to the approval of Saudia HR Department". In these most recent of circumstances it is unlikely that the "Contract Completion" bonus will be paid even to pilots who are leaving at the normal end of their contracts.
Other changes affecting renumeration of expat pilots are likely to follow as part of the KSA government's budget reduction and cost reduction programs.
