Seems I was too optimistic. 
Mine reached destination hub this morning around 5 am. Still have not received a call for the delivery date yet. So the last step is the slowest in the chain.
Seems Bambu chose avis by phone instead of avis by call of delivery driver which results in a 24-hour runtime extension according to their terms. 
Expect mine to be delivererd on Monday now. 
Still faster than Bambu’s ETA of April 8th.
