Airbus is planning to increase planned production for the largest member of its A350 family to power its next important struggle with Boeing for a lucrative corner of the jet market, Reuters has reported, citing two people familiar with the matter. The largest variant, the 350-seat A350-1000, will allow Airbus to compete directly with the twin-engined 777 "mini-jumbo." Airbus blames a shortage of delivery slots for slow sales of the A350-1000, which has notched up 88 orders and seen several cancellations since launch, though its US rival claims Airbus was wrong to try to compete in two segments with one plane. Raising production would free up more slots to be sold. "Airbus is looking at ways of increasing A350-1000 production," one person said.
