A rounding error, but still worthwhile. $300k here, $300k there, and pretty soon you're talking about real money ;).
Anyways, the main point: passengers and their luggage on a 737-sized craft might weigh 15,000 kilos. You might save 340 kilograms/hour by flying slower, too, so a 6 hour flight without passengers could move 17 tonnes more than it did with pax onboard, so long as you have space for what you're shipping.
