Japanese lessor SMBC Aviation Capital and Singapore-based lessor BOC Aviation placed orders Tuesday at the Farnborough Airshow for a total of 158 Airbus A320 family aircraft.

SMBC signed a firm order for 110 A320neos and five A320ceos. CEO Peter Barrett said it was the largest-ever single firm order placed by a leasing company for narrowbody aircraft. The order brings SMBC’s total A320 family orders up to 206 aircraft.

The ceo deliveries will start in 2016 while neo deliveries will begin in 2017. Total order list price value is $11.8 billion.

BOC’s order was for 43 A320 family aircraft made up of seven A320neos and 36 A320ceos.  The ceo deliveries will start immediately, BOC Aviation CEO Robert Martin said, while neo deliveries will begin in 2019.  

“We have customers actively seeking the ceo, particularly the A321, in Asia-Pacific, especially among people who don’t want to wait a number of years for the neo version,” Martin said.

Airbus president and CEO Fabrice Brégier said there was now an industry bottleneck for the A321, but the manufacturer is ramping up production to meet increased demand for this variant. Airbus COO, customers, John Leahy told ATW that slots for A320neos was now “extremely tight.”
