Fuel Dumping: the basics

“Fuel Dumping” is the term generally given to when an aircraft disposes fuel mid-air prior to landing. This often occurs when a plane is forced to make a landing short of its intended destination to lighten the aircraft’s weight.

 

However, there is another more secretive meaning to the term “Fuel Dumping”. It involves intentionally pairing two separate flights on the same airfare ticket in the hope that the fuel surcharge component of the main, more-expensive flight is either partially or fully dumped/eliminated. Have a read of this previous blog post to gain a better understanding of the fuel surcharge component and why it exists.

 

We will now go through the basics of “Fuel Dumping” which will help you better understand this practice and the steps needed to successfully achieve a “dump”. Please note, this article is strictly for educational purposes only.

 

Here are the stages needed to make a successful dump:

 

1. Find a Candidate Fare
A good candidate fare consists of a very low base fare and a high fuel surcharge. This is because even if you manage to dump the fuel surcharge, you will always have to pay the flight’s base fare and tax. If the base fare is very high (blue box in the image) then there’s less reason to dump the flight. Eitaexplainven after removing the fuel surcharge, there would still be a significant amount to pay. The ITA Matrix website allows you to view the price breakdown for any flight.

 

Once you have found a flight with a low base fare and high fuel surcharge, you must then find out if the flight is actually dumpable – because not all flights are.

The fare rules determine what a particular flight can and can’t do. For example, how many stops are permitted; the required minimum stay; costs associated with changes. Again, the ITA Matrix website allows you to view the fare rules by clicking “rules” beside the flight details (green box in the image).

 

Within the rules, the “Combinability” section determines whether the flight is dumpable and what specific rules are associated with it. If “END-ON-END COMBINATIONS” and “SIDE TRIPS” are both permitted, then you have likely found a dumpable flight.

However, within each of these, there may be certain restrictions. For example, “END-ON-END COMBINATIONS PERMITTED WITH FARES WITHIN AREA 1” means you can combine this flight with another flight only from North America (Area 1 is the industry’s code for North America).
So you’ll be completely wasting your time if you attempted to dump this flight with a smaller flight in Europe or Asia, because only North American flights are combinable with this particular fare.

 

So now you have found a flight with a low base fare, a high fuel surcharge, and permitted combinability rules, you can proceed to the next stage.

 

2. Finding the Strike

The extra flight added on to the itinerary that causes the fuel dump to occur is called the “strike”. This flight should be short and inexpensive, otherwise it defeats the purpose of this whole practice. The strike can occur anywhere in the world with any airline, so searching for it will take a significant amount of time. Always try to aim for strikes that are less than 60 minutes long in flight duration. Remember, some dumps are OTA specific so it’s recommended to search using a flight aggregator like Momondo. You will have to use the multi-destination search option, as you are inputting at least 3 separate legs.

There are a number of places you can position the strike in your itinerary.

The most common are:

 

-before the main flights (1x)
-after the main flights (3x)
-inbetween the main flights (2x)
-both before and after the main flights (1/4x)

 

 

Typically, 1x strikes have the most successful results often achieving a 100% fuel dump. The downside to the 1x is that because this flight takes place before the main flight, you typically MUST fly it, even if it departs on the other side of the world. If you do not show up for your 1x strike, the rest of your ticket is automatically cancelled.

In this Expedia image, you can see a 1x strike is used to dump the fuel surcharge on the New York, USA to Colombo, Sri Lanka round-trip flight with Emirates. The fuel surcharge is completely eliminated, leaving the customer with only £184 (approx $259) to pay.

We have blacked out the strike details.

 

 

3. Booking your ticket

If you decide to book a fuel-dumped ticket, you must understand the risks involved. Fuel dumping enthusiasts who regularly fly these types of tickets, minimise the amount of human interaction involved with their booking. Calling the airline’s customer service department for a date change or a refund is only asking for big trouble. A knowledgeable airline employee will notice the irregular itinerary, so it’s highly recommended to simply book your tickets, check-in online and fly.

Many newcomers to this practise are often concerned about the consequences of being caught by an airline. In theory, if an airline notices your fuel-dumped ticket, they could deny you boarding unless you paid the full ticket fare.
