I am currently flying from KEWR to ZSPD, I have just departed, and on the ground it said that I had enough fuel for 15 hours 45 minutes but now one hour into the flight, I am cruising at FL350 and at M.85 but it says I only have 9 hours of fuel remaining. Is this because the aircraft is heavy? Previously when I flew the 787-9 long range I did not have this issue. Is this normal?
Thanks
