- Emirates president Tim Clark says the oil is "hugely overpriced" and should be at $52 per barrel.
- The airline boss says market levels for spot and oil futures suggested that oil had peaked in price for now.
- Clark adds that he hopes to know more this week about a flight that arrived in New York on Wednesday with dozens complaining of illness.
Airline fuel is overpriced, and the underlying cost of oil should sit around $52 per barrel, Tim Clark, President of Emirates told CNBC Friday.
"I am one of these people that says it is hugely overpriced. If you are at $77 or $83 dollars (per barrel) it should be at $52. That's where it needs to be," Clark said in an interview with CNBC's Joumanna Bercetche on the side-lines of The Aviation Festival in London.
"Those people, those countries, those entities that say they can't make money on $52, they need to be doing something else," he added.
Clark added that as spot prices for oil were now roughly matching the futures price, the market had sensed the oil price was unlikely to rise further from this point.
"I think fuel is now capped out. The forward curve is flat," he said before adding "There's a certain amount of flakiness going forward that fuel will rise above where it is today. That's my view," Clark said.
Emirates, which employs approximately 25,000 cabin crew staff around the world, has seen growth hampered by a prolonged period of lower oil prices in recent years — a key driver of wealth in the Gulf region.
Clark said fuel prices for his airline were now running at roughly 44 percent higher than the same time last year. However, he warned however that many oil producers weren't exhibiting a traditional response to a higher price.
"As the oil producing countries, largely in the Middle East get a benefit of that, historically there was an uptick very rapidly in demand, but we are not seeing that," Clark said.
He added that many emerging markets and Middle East countries were struggling to match the performance of the United States and global growth looked uncertain.
"One has got to worry a little bit about what is driving all of this. Whether it is an inordinate amount of debt creation and that is likely to take its toll. We saw that ten years ago," he said.
On Wednesday Federal health authorities and local police quarantined an Emirates Airline jumbo jet Wednesday morning in New York after several passengers said they were ill.
Flight 203 arrived in New York with around 100 travelers and flight staff complaining of cough, fever and "symptoms of gastrointestinal illness," according to the U.S. Centers for Disease Control and Prevention. 11 people were then taken to hospital as an additional precaution.
Clark told CNBC that no source for the sudden outbreak of sickness had been found as yet, but he expected to discover the root of the problem "within a week."
The Emirates president added that he didn't expect to lose custom over the incident before adding that the airline was an extremely safe organization that "prides ourselves on health and safety."
