Lessor CIT has become the latest customer to switch allegiance away from the Airbus A350-800 towards the larger -900.
The leasing company has also reduced its A350 order by two in the process.
CIT originally had orders for five A350-800s and two A350-900s. But Airbus's backlog data shows the lessor has revised its order to five A350-900s.
Given that the airframer has only recorded a single cancellation for the -800, this suggests CIT converted four of its -800s to -900s, cancelling the remaining -800 and a single -900.
CIT's revision takes the A350-800 backlog down to 135 aircraft.
Airbus has pushed back development of the -800. The airframer insists it is committed to building the twinjet despite the lack of -800 orders over the last three years and gradual migration of previous orders towards the larger -900.
There are firm orders for 567 A350s, including 357 -900s and 75 -1000s. The -1000's development schedule has also slipped by two years after Airbus opted to increase its engine thrust and range.
