QANTAS Boeing 737-838 VH-XZK operated a Perth – Cloudbreak Fifo sector as QF1390 this morning then instead of operating the return QF1391 back to Perth it instead operated the QF1385 Cloudbreak – Perth Fifo sector. The swap was due to the diversion and subsequent late running of this morning’s QF1384 Perth – Cloudbreak Fifo sector.
