Delivered to Qantas in November 2014, Boeing 737-800 VH-XZP features the airline's early 1970's livery as worn by their first Boeing 747's.
The aircraft made its first flight to New Zealand back in July 2015 with a one off trip to Auckland http://mrcaviation.blogspot.co.nz/search?q=VH-XZP and I think this had been its only foray across the Tasman.
Until 10 January 2017 when the jet stepped in to cover for a Jetconnect 737 as QF123 from Brisbane to Auckland and returning to Brisbane as QF126.
The airline has a second Retro Roo in operation, VH-VXQ
