Narrative:
Flight plan from egll to ZZZ with inaccurate fuel scores between several fixes after coast in near yqx. One leg in particular between steam and yri had 1 hour 14 min flight time with a fuel burn of only 10.7. Actual fuel burn was closer to 15.0. There seemed to be several significant errors. Our planned arrival fuel was planned at 17.0. We stayed high and received shortcuts on our route and arrived at ZZZ with 11.5. Our support from dispatcher was excellent. Someone needs to look into and determine where the automated flight plan went wrong.
