No rumour. They were planned over the top with 8. (Maybe 7.9... last week so I can’t remember anymore!) That’s at least 1.5 hours over min reserves of 30 min so closer to 120 minutes over the top. Given the low fuel flow of the 787 and the lower ZFW of these flight I suspect 8.0 is probably closer to 135- 140 minutes. No idea what they were on blox with.
Interestingly the flight a couple of days ago was planned at 17:35 flight time. Originally had 4.4T over the top. They had space to load additional fuel (which they did). Would have ended up closer to 6.0- 6.5 over the top.
