Shares in Qantas slumped to an 18 month low after the Australian airline warned of big losses and announced 1,000 job cuts.
Qantas said a "marked deterioration" in trading conditions meant it was on track to make losses of up to A$300m ($271m; £165m) in the current half of the year.
It is struggling with fierce competition from rival Virgin Australia.
