Does anyone know how often a shorthaul commercial airplane (737 / 320) takes on fuel? After every flight or just once a day?

Thanks if you can inform on this question! Geert

could be every flight, could be just the every other one... it depends on the load and time that is allowed to turn the aircraft. Also, the next station in line, and how far away it is determines the fuel required. the ONT-PHX-ABQ run, they load up 35,000 or so pound of fuel to run both legs. but delays can occure, so if the aircraft is low on fuel at the next downline station, then fueling is mandatory.

In our operations (Uk Charter 757/767) we typically refuel on every leg. We do tanker fuel, however, to places like the Canary Islands due to the high relative cost of fuel at the destination.

Typically in this case we load enough fuel to plan a landing at MLW. This does not remove the requirement to refuel for the return trip, but means we need to upload less fuel (at the higher cost) since we still have a lot of (cheaper) fuel on board.

The penalty is increased weight on the outbound flight so some of the tankered fuel will be burned purely to carry it. On the 757 every 1,000kg more fuel loaded increases fuel burn by about 50kg/hr.

So there is a formula the dispatchers use to calculate the optimum amount of fuel to tanker based on trip length and relative fuel cost at the destination, to achieve the minimum trip cost.

Pull this on a 737, and you're going to be arriving in ABQ with about 25,000 fuel aboard, which (depending upon what model of 737 and the ABQ temperature is) will very likely leave you overweight for either performance-limited landing weights, or maximum quick-turn landing weights.

Bottom-line: Thou must watch thy tankering fuel into "hot-and-high" airports, lest thou sitteth eons awaiting to defuel...

Otherwise, Rick said it all... FYI, "fuelstops" are really another thing, defined as planning to go ABC-XYZ on a scheduled flight and it can't make it non-stop for some reason (high payloads, etc.), and you have to "fuelstop" someplace in between.
