Airbus' June 2013 orders and deliveries report shows that United Airlines cancelled 7 A319s and 5 A320s, leaving it with 16 A319s and 14 A320s remaining on order.
United Airlines has one of the oldest orders in Airbus' backlog, having last ordered A320-family aircraft in May 2001. United took delivery of A320-family aircraft at a steady pace beginning in November 1993, but deliveries ended abruptly in October 2002.
In addition to the cancellation, Airbus' report shows another decline in the backlog for the A330-200F. Aircraft lessor Intrepid Aviation switched an A330-200F to an A330-300, bringing its A330-200F backlog down to five. Total A330-200F orders now stand at 45 with 22 delivered.
