That's giving them too much credit. They could have another month to produce the models and the printing would still be effed if they decided to be lazy. There have been other batches of models with errors that were not released around the CNY holiday.Rushing the releases isn't helping - this month's set is a good example - at least 2 highly anticipated A350s have wrongly positioned Cockpit printing, and the 777s are now wearing oversized sunglasses.
Somewhere there's been a gap in sampling and approvals due to the rush to ship domestically before their CNY holidays.
