DUBLIN, Jan 15 (Reuters) - The CEO of fast-growing

aircraft lessor AviLease on Wednesday said he expects Boeing ( BA )

and Airbus to get their supply issues under

control in the next four years and said he will be opportunistic

about possible aircraft orders.

AviLease , backed by Saudi Arabia's Public Investment Fund

(PIF), plans to increase its balance sheet from around $8

billion to around $20 billion by 2030, through acquisitions of

rivals, buying individual planes and "potentially" doing large

orders, Chief Executive Ted O'Byrne said.

Buying from the large manufacturers "is clearly part of the

playbook", O'Byrne told the Airline Economics conference in

Dublin. "There again, you have to be opportunistic."
