DUBLIN (Reuters) - The CEO of fast-growing aircraft lessor AviLease on Wednesday said he expects Boeing 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."
