How spot on is expertflyer in determining the punctuality of flights?
I'm trying to change from BA12 SIN-LHR to QF9 SIN-LHR. Having flown QF9 quite a few times I've usually arrived in LHR very punctually. But EF says that QF9 is late 25% of the time with the average delay being 72 mins
shock:!), whilst BA12 only has a 5% chance of being late with an average delay of 8 mins.
I'm trying to fit in a day trip to Nottingham before flying off to DXB, so the more logical choice seems to be BA12.
But can someone advise me on whether I should trust the EF stats?
