Air Lease Corporation (ALC) has confirmed it will purchase up to 33 airplanes from aviation giant Boeing at the Paris Air Show.

The agreement calls for 14 firm orders and four options for Next-Generation 737-800s, as well as five 777-300ERs (Extended Range) and four 787-9 Dreamliners.

ALC has also agreed to exercise options on six airplanes from last year’s 60 737-800 order.

“We continue to build the foundation of our growing commercial lease fleet with these Next-Generation 737s, 777-300ERs and 787 Dreamliners,” said Steven Udvar-Hazy, chairman of Air Lease Corporation.

“These modern, fuel-efficient airplanes will provide our airline clients the capabilities to perform their missions in the most economical, reliable and environmentally responsible manner.”

The 777-300ER extends the 777 family’s span of capabilities carrying 365 passengers up to 7,930 nautical miles (14,685 km).

The 787-9 will seat 250-290 passengers, 16 percent more than the 787-8, with a range of 8,000 to 8,500 nautical miles (14,800 to 15,750 km).

“Air Lease Corporation’s management team has a proven track record in global airplane leasing,” said Boeing president Jim Albaugh.

“This agreement demonstrates their disciplined approach to building a fleet of young, high-quality, high-demand airplanes.

“It is impressive how Air Lease Corporation has positioned itself for success since starting business early last year.”
