fuel prices

Air New Zealand chief executive Greg Foran told Checkpoint that the price of fuel "has moved pretty quickly". 

"Over the last few months, we've seen effectively a doubling in price and I've referred to the fact that getting to Los Angeles, it used to cost us just over US$40,000 to fill up a Dreamliner and now it's about US$96,000, so that's seen the price of tickets on average increase around 20 plus percent."

For a drone attack to have knocked half of its - and 5% of the world's - oil supply offline, speaks to the vulnerability of their plants and in turn to the vulnerability of a vital part of the global energy infrastructure.

The Khurais oilfield produces about 1% of the world's oil, and Abqaiq is the company's largest facility - with the capacity to process 7% of the global supply.

Questions being asked centre on why this attack could not have been prevented by a company with such deep pockets and whether it can happen again.
