Mitchell Ring and Jennifer Colin say woman who died en route to Doha was left next to them by Qatar Airways staff.
Mitchell Ring said a passenger died part-way through the 14-hour flight from Melbourne to Doha last week.
Ring said he was seated with the body for around four hours despite other empty seats.
Ring said he was made to wait next to the corpse even after the plane landed.
“The ambulance officers and the police came in, and the ambulance officers started pulling the blankets off the lady,” he said.
