Boeing Co said on Tuesday that it took an order for 38 Next-Generation 737 airplanes and purchase rights for seven additional 737s from leasing company CIT Aerospace.

The order -- potentially worth $3.2 billion -- includes 15 737-900ERs and 23 737-800s. Boeing said it was the largest order placed by a leasing company for the 737-900ER, the largest and newest member of the Boeing Next-Generation 737 series.

Deliveries are scheduled into 2017. Boeing gets paid for airplanes at delivery.

CIT owns or finances a fleet of more than 300 commercial planes, of which 140 are Boeing airplanes.

CIT now has a total order book of 111 aircraft.
