On a recent flight home from Bali my son left his Nintendo Ds XL in the seat pocket in front of him. We realised early and attempted to contact Jetstar within two hours of the plane landing with flight and seat number. Six phone numbers and four hours later no success with from anybody willing to listen. It's been seven days and I'm still waiting for a return call that was supposed to be within 24 hours. According to one Jetstar employee the controls are so strict that it is nigh on immpossible for cabin or cleaning crew to remove anything from the plane that would not be detected. He advised that cleaning crew are actually patted down. This same employee in the next breath advised that the chances of getting my property back were 'slim'. When asked for an explanation regarding the contradiction in his previous two sentances I was given another number and told to try them. I am still waiting for a response to my email but I am not expecting one. Whilst it is not Jetstar's fault the property was left in the plane I cannot understand why it is so difficult to get my propery back or to even get a straight answer to where it is. My husband was last off so no chance it was another passenger, that leaves cabin crew or cleaning crew. Unfortunately, I think that the statement that the chances of getting my property back are slim. I have been advised by a travel agent that Garuda have recently won some awards and that Qantas engineers service their planes. I doubt I will be flying Jetstar again.
