Looks like N673US is planned to operate DL 621 NRT-SIN on 16 October and enter the shop for modifications.
N673US is the last unmodified DL 747-400 and this flight will represent completion of the 747 fleet modifications from a customer perspective - there will no longer be any unmodified 747-400s in passenger service.
That is oh so sweet! Thanks for all the updates.
