B788 VH-VKH on JQ64, the Monday 20 May 2235 hours redeye from SGN down to MEL was not airborne until 0608 on Tuesday 21. Arrival should be at 1606 hours, 476 minutes late. This is due to JQ63, the mid afternoon Monday 1515 hours northbound (MEL up toSGN) not pointing skywards until 2212 last night.
Yesterday the aircraft arrived MEL at 1953 hours, seven early on JQ44 ex Beli's DPS so it looks like it was substituted for a failed member of the same B788 class.
A further consequence is that JQ17, the 1450 hours MEL - HKT is predicted to depart at 1730 so pretty close to minimum turnaround times for aircraft VKH. JQ18 returning overnight from coughet cannot help but be delayed, so patience will be required up there.
If any AFFer was on this soutbound today, were hotel rooms provided in Ho Chi Minh City? One problem would be if JQ did not know the extent of the delay (i.e. it kept changing), it'd be difficult to predict when passengers would be required to be at the SGN airport.
