IFR flights must have enough fuel at takeoff to fly to their destination and then their alternate plus 45 minutes for variations in routing/winds. Airlines may load some extra for expected ground delays, but too much means burning more fuel to carry extra weight around, which adds up fast for thousands of flights per day. They'd rather occasionally return to the gate for a top-up--and to give angry passengers a chance to deplane. | |
