More than 80 per cent of Tigerair pilots were set to take disruptive action on Friday, refusing to fly aircraft with allowable defects or fly hours outside their roster.
Members of the Australian Federation of Air Pilots and VIPA, a union for Virgin Australia Group pilots, planned to take the action after 12 months of negotiations over pay and conditions.
AFAP executive director Simon Lutton said the actions could cause delays and cancellations for Tigerair passengers.
