A computer glitch in the Qantas passenger check-in system has delayed the departure of several flights from the Perth international and domestic airports.
Qantas says the system has been crashing intermittently across the entire network.
Staff have been forced to manually check-in all passengers, which is causing delays of at least two hours.
Anna Giardina was meant to depart on a flight to Sydney shortly after 10:00am (WST).
She says Qantas staff have been less than helpful.
