3:27 pm Canceled China flights top 85,000

Airlines have canceled more than 85,000 China flights because of outbreak, according to aviation consulting firm Cirium. That count is set to rise in the coming weeks as more than a dozen international airlines have scrapped or reduced China service altogether. The cancellations, logged between Jan. 23 through Feb. 11, account for more than a third of scheduled flights, to, from and within China, Cirium said. Close to 20% of international flights to and from China, or 9,239 trips were cancelled, and 37%, or 76,338 flights were canceled. The impact will likely dent airlines' first-quarter results as they process refunds to customers booked on those routes.

9:12 am: Boeing sees hit to airline profits, stagnant air cargo market due to coronavirus

The global air cargo industry is unlikely to grow this year because of the challenges in the China market due to the coronavirus, a senior executive at Boeing said. The coronavirus crisis has dimmed hopes of a rebound for air cargo after its worst year in the decade since the financial crisis, the International Air Transport Association, a group of 280 global airlines, said last week. Travel restrictions to and from China and a more than two-thirds drop in capacity offered by Chinese airlines will hit airline revenues, said Ihssane Mounir, the planemaker's senior vice president of commercial sales and marketing. "China has reduced capacity by 70%; that is money, that is revenue," he told reporters at the Singapore Airshow, whose attendance has been sharply reduced as dozens of companies stayed away due to concerns about the virus. — Reuters

8:14 am: OPEC slashes oil demand forecast

OPEC has dramatically lowered its forecast for oil demand growth this year, citing China's coronavirus outbreak as the "major factor" behind its decision. In a closely-watched monthly report published Wednesday, the Middle East-dominated producer group downwardly revised its outlook for global oil demand growth to 990,000 barrels per day in 2020. That's down by 230,000 bpd from the previous month's estimate. The amended forecast is likely to reinforce the case for OPEC and allied non-OPEC producers, including Russia, to impose additional output cuts sooner rather than later. "The impact of the Coronavirus outbreak on China's economy has added to the uncertainties surrounding global economic growth in 2020, and by extension global oil demand growth in 2020," OPEC said in the report. — Meredith
