United Airlines (UA, Chicago O'Hare) has signed an agreement with AerCap to lease up to twenty-five A319-100s over the next seven years. The carrier said in a statement that eleven aircraft would be delivered over the next two years followed by up to 14 more aircraft which may be delivered over the next five years subject to certain conditions.

"These aircraft will supplement our current fleet of fifty-five A319s and fly routes across our domestic, Caribbean and Latin American network, ultimately helping us reduce dependence on 50-seat regional jets," it said.

The aircraft, currently in service with China Southern Airlines (CZ, Guangzhou), will begin arriving in early 2016. Once in the US, United plans to overhaul them in terms of both maintenance as well as on-board product.
