That was what the GA said. When talking to the SD on the delayed flight she said there were also issues with seats, and the nail in the coffin was that a jump seat also broke… I guess tough to take it out for refurb as she said that 4 of the type are in for heavy maintenance right now.
So this is not correct, which further emphasises why taking what they say has to be done with a large grain of salt. 940 is in HKG while 946 and 948 (the two former SQ birds) are not yet in the fleet. The discussion about the delays for the 931 refurb relate to delays in supply chain for seats, but who really knows. It is likely all 16 will be active in fleet for the summer based on the demands of the schedule.
