Singapore Airlines low-cost subsidiary Scoot is considering extending the lease of some Airbus A320ceo aircraft due to problems with their Pratt & Whitney engines, Chief Executive Leslie Thng said. "We have some flex in terms of the A320ceos that we are returning next year in 2024, so we are exploring whether we should maybe extend some of the leases to mitigate the impact," Thng told reporters ahead of the Association of Asia Pacific Airlines' annual meeting, which starts on Thursday in Singapore. As at end-September, Scoot said it has 20 A320ceo aircraft on its fleet.
