I am about to book a flight for myself and family for mid October on QF93. I believe we will be flying in an A380 plane. My question is, although we will be seated in economy, do the seats back there have any USB charger, power outlets etc to charge up devices such as an IPAD or laptop? Obviously I would have to provide the cable. What are the entertainment systems each seat have like? How many movies are available? Is there any web site that provides details on what I can expect?
