JetConnect Boeing 737-838 ZK-ZQG, which has been under maintenance at Brisbane since 31st October, returned to service this afternoon operating QF573 Brisbane – Perth. The aircraft has been re-registered VH-VYZ and is now part of the QANTAS mainline fleet. The aircraft was originally ordered as QANTAS VH-VZN but that registration has since been taken by a hot air balloon.
