DUBLIN, Jan 23 (Reuters) - Airlines face a shortage of the industry's large long-haul jets into the next decade, aircraft leasing company Avolon said on Friday.

Avolon, one of the three Irish leasing companies that together own and lease out about a sixth of the world's passenger aircraft, said in its annual outlook report that the shortage of narrow-body jets was slightly less acute but would also last until the end of the decade.

"We're forecasting the narrow-body market to be undersupplied through the end of the decade, into the 2030s and perhaps a longer period of time for the wide-body market," Avolon Chief Risk Officer Jim Morrison said ahead of a major gathering of aviation financiers in Dublin next week. 

WIDE-BODY DELIVERIES ARE HALF PRE-COVID LEVELS

About 4,000 fewer jets than planned will be built this decade because of the COVID-19 pandemic and other production disruptions, Avolon estimates.

The delivery of 1,183 narrow-body jets last year was just short of the pre-COVID peak, but the 174 wide-body aircraft deliveries were about half of pre-pandemic levels, according to Cirium data cited by Avolon.

"The structural undersupply of wide-bodies will last longer than the market anticipates and will be felt more acutely as international markets continue to drive traffic growth," Avolon's report said, referring to non-U.S. markets. 

While China has driven demand in recent years, the key markets for aircraft in the coming years will be India, the United Arab Emirates and Saudi Arabia, the report said. 

The shortage has constrained airline capacity, allowing carriers to raise fares, and also led to bottlenecks in engine repairs and left hundreds of planes grounded waiting for maintenance.

A fourth consecutive year of profitability, boosted by lower fuel prices, is set to put the industry in a good position to weather heightened global uncertainty and recession risk, the report said. 

"If there was a period of lower economic growth, for whatever reason, we actually believe the industry is well positioned to withstand that," said Avolon CEO Andy Cronin.
