Struggling with pilot and spare parts shortages, US airlines are facing another challenge - a shortage of new planes amid delivery delays by Boeing and Airbus.

"APA-Economics" informs about this with reference to "The Wall Street Journal".

Top airline executives and industry officials say planemakers are delaying deliveries of new narrow-body planes often used on domestic U.S. flights and other short-haul routes.

Due to this, air carriers are unable to increase the number of flights to meet the increased demand and plan their schedules.

A Boeing spokesperson said the company is working closely with suppliers to fulfill its commitments to customers.

In addition to supply issues, Boeing is facing regulatory challenges with its 737 MAX planes.

The company is waiting for the approval of the Federal Aviation Administration (FAA) to use the mentioned aircraft until the end of 2022.

Airbus management also says it is working to resolve supply chain issues.
