My colleague was to join QR on AIRBUS fleet as DEC, his DOJ was changed two times already, not too much, around 2-3 weeks each time, finally he received next DOJ for beginning of the April, one day before joing and reporting in Doha he got cancellation that DOJ and directed to the talent pool for nor specified time. Be careful when You guys deal with QR, not to put any thrust on them, they do whatever they want.
