The difference from 'flight time' matters on short legs: a 45-minute hop can be an hour-plus of block once taxi and departure sequencing are counted, and at $3,000+ per hour the distinction is real money. Our indicative engine pads great-circle flight time for exactly this, which is why wizard estimates track final quotes closely instead of surprising you upward.
Block time is also why the faster aircraft sometimes wins on price: past roughly 1,500 nm, a super-mid's speed can buy back enough billed hours to beat a cheaper hourly in a slower cabin — the wizard runs that math per route automatically.
