The Export-Import Bank of the United States (Ex-Im Bank) has approved a final commitment of $1.1 billion to finance the export of a fleet of Boeing 737-900ERs. The aircraft, with CFM International engines, will be exported to Indonesia’s largest privately owned airline, Lion Air.

The financing will support a portion of Lion Air’s outstanding orders for the 737-900ER, which includes 230 Boeing 737 aircraft ordered in November 2011—the largest commercial aircraft order in aviation history. Lion Air is the launch customer for the 737-900ER and will be the largest operator of the type.

The aircraft will be delivered to Lion Air, Malaysia’s Malindo Airways and Indonesia’s Batik Air.

Lion Air president and CEO Rusdi Kirana said this “substantial final commitment … positions the Lion Group and Transportation Partners for future growth across the ASEAN [Association of South East Asian Nations] region.”
