Recently had a horrible flight on Qantas fron Sydney to Santiago, Chile.
The entertainment system on the plane failed shortly after the very late take off on the ageing Qantas plane allocated to the flight. This made for a flight full of agitated customers. The flight was at full capacity due to the cancellation of another flight.
The whole flight experience was an absolute nightmare with the cabin crew struggling to maintain basic passenger expectations.
Consider using an airline with a modern fleet that deliver on services for the paying customer. Never again on those very old Qantas planes that seemed to have commenced flying service way back in the 80s.
