KUALA LUMPUR, Aug 29 (Reuters) - Malaysia Aviation Group

(MAG), the parent of national carrier Malaysia Airlines, said on

Thursday it would reduce network capacity by 20% across its

airlines this year amid a shortage of planes, labour and parts.

The group, which also operates carrier Firefly and Muslim

pilgrimage service provider Amal, said in a statement the

reduction would involve domestic flights as well as routes in

Southeast Asia, North Asia, Australia, New Zealand, Greater

China, South Asia and the Middle East.

"While it is a difficult decision, our focus is to

prioritise customers first, ensuring we can deliver credible

flight schedules and ensure the best possible customer

experience moving forward," MAG said.

MAG said this month it would temporarily reduce flights

across all of its carriers until December following a string of

service disruptions this year.

Malaysia's civil aviation regulator this week cut the

duration of Malaysia Airlines' air operator certificate to one

year from three years following a probe that found significant

technical issues at the state carrier, including a shortage of

skilled labour and mechanical parts.

MAG said it would work closely with regulators and

manufacturers to address operational challenges and ensure

timely and reliable delivery of spare parts.

A global shortage of parts has also affected deliveries of

new planes, which has impacted the group's flight planning, MAG

said.

It said it had received only four Boeing 737-8 aircraft out

of 13 expected this year.

Similarly, it was scheduled to take delivery of four A330neo

planes from Airbus in 2024, but will now receive only three by

the end of the year, MAG said.
