A protester who refused to take her seat on a plane until an asylum seeker headed for deportation was removed has been asked to pay Qantas more than $3000 in compensation.

Jasmine Pilbrow, 22, boarded a Qantas flight from Melbourne to Darwin in February 2015, believing an asylum seeker passenger on the plane was en route to being deported to Sri Lanka. Pilbrow refused to sit down as flight attendants were preparing for the plane to take off.

Two other passengers – who were not charged over the incident – also stood up. The asylum seeker and Pilbrow were removed from the plane, which was delayed by almost an hour.

On Friday, magistrate Meagan Keogh found Pilbrow guilty of interfering with a crew member and asked her to voluntarily pay Qantas $3429, which the airline argues it lost because of the incident, including fuel costs and delays to a number of flights.
