I am trying book a flight from Singapore to Perth on 20/12 leaving 5.50 pm on a Jetstar flight and whilst I can add on a meal etc, book my seat, there is no place to buy the IFE. As I want to purchase this prior, where can I do this? I called Jetstar but the woman was not that helpful advising me I could do this online but I am unable to find where I can add it in on the booking form?
