Wisdom of crowds and all that, i’m guessing around $30k ? My working was: +2 hours (a path that should take 0.5 hours took 2.5h according to flight radar) According to a random aviation site, an unspecified 747 revision at unspecified altitude with unspecified engines burns 4 litres per second, so take that with a bag of salt! Jet A1 fuel at $1/litre-ish $30k-ish ?
