Dublin-based operating lessor Avolon Aerospace is requesting US Export-Import Bank support to finance Boeing 777 aircraft.
According to the export credit agency, a decision will be made after 26 July.
No further details were provided about the request.
Separately, earlier this month, a US bankruptcy court approved a sale and leaseback deal for two Boeing 737-800s between American Airlines and Avolon.
The aircraft (MSNs 33323 and 33233) will be delivered in October and in January 2014 to Fort Worth-based American, according to court documents.
