It appears that the DL 744 interior modifications have been completed as N673US(#16) should re-enter service SIN-NRT on Nov13. On Nov12 a previously completed aircraft N662US, should re-enter service on the same route. These two aircraft are to be replaced by a 763-ER showing NRT-SIN on Nov11 and another 744(previous mod) on Nov12. Looks to be some unfinished or new work on 3 of the 744's being done as this is the 3rd aircraft to return to QPG(WSAP).
It's interesting to see the 763 on a one way trip into SIN--perhaps some of the modifications will be done there as well as HAECO?
