DUBLIN, Jan 13 (Reuters) - Delays in deliveries from

major aircraft manufacturers are in some cases getting worse,

and estimates of delay time can not be trusted, Steven

Udvar-Hazy, the executive chairman of Air Lease Corp ( AL ) said

on Monday.

"Supply chain bottlenecks, OEM delays .. in some cases, are

getting worse," Udvar-Hazy told the Airline Economics

conference, using the term Original Equipment Manufacturer,

which is used to refer to large manufacturers such as Boeing ( BA )

and Airbus.

"You can't trust those notices," he said of delay notices

from aircraft manufacturers are systematically extended.
