What is an override commission? Supplier overrides explained

An override commission is extra commission a supplier pays on top of the base rate, usually to the host agency, consortium or agency that holds the agreement. The American Society of Travel Advisors (ASTA) says overrides are typically calculated as a percentage of the same commissionable base as the advisor's commission.

Here is how overrides work, what counts toward them, a worked example, who earns them, and how to find out whether any of it reaches you.

What is an override commission?

It is a second layer of commission. The base commission pays for the booking. The override rewards the organization behind it.

The US Government Accountability Office (GAO) described airline overrides in 1999 as additional commissions, called overrides, to travel agencies that exceed sales targets. ASTA's May 2026 brief places them with host agencies and consortia, the groups above the individual advisor.

How does an override commission work?

The override rides on the same commissionable amount as your commission. ASTA gives a worked example: a $2,000 booking with $1,600 commissionable after NCFs. In it, an advisor earning 10 percent commission generates $160, while a host agency and consortium earning 3 percent and 2 percent overrides receive $48 and $32.

Non-commissionable fares (NCFs) are the part of the price that a supplier designates as non-commissionable, meaning the travel advisor receives no commission on that portion. Because overrides share the base, ASTA says they are similarly reduced when NCFs are applied. See what is an NCF.

That money matters beyond the host's books. ASTA says override revenue helps fund marketing, technology investment, and advisor support.

What counts toward an override?

Volume, measured on commissionable revenue. ASTA describes override programs as typically tied to total revenue, and says host and consortium override structures are tied to total commissionable revenue.

What counts as commissionable revenue is set by each supplier. Aman at Sea's trade policy is a public example. Its commissionable revenue is the published Voyage Fare minus items that include discounts, onboard credits, net rate groups and most cancelled bookings. Commission is payable within thirty (30) days after a voyage sails.

What this means for advisors: a booking that pays you little base commission also adds little to your host's override volume. Cancellations and discounts shrink both.

Worked example: how a tiered override plays out

This is illustrative arithmetic. The tier thresholds below are made up. The 3% and 2% rates come from ASTA's example.

Say a cruise line pays your host a 3% override, but only once the host's commissionable sales with that line pass $1 million in a year. Your client books a $2,000 cruise with $1,600 commissionable.

1. Your base commission. 10% of $1,600 is $160, paid to the host and shared with you under your split.
2. The host's override. If the host has passed the threshold, 3% of $1,600 is $48. If not, your booking still counts toward reaching it.
3. The consortium's override. At 2%, the consortium earns $32 on its own agreement.
4. A cancellation. If the client cancels before sailing, your $160 and the $48 override can both disappear. The booking also drops out of the volume total.

Across a year, this adds up for the host. For you, the override matters only if your contract shares it.

Who earns override commissions?

The organization that signed the agreement with the supplier. In practice that is one of three:

1. Host agencies. In ASTA's example, the host earns a 3 percent override on the advisor's booking.
2. Consortia. The consortium in the same example earns 2 percent.
3. Agencies with their own deals. ASTA notes some travel agencies have negotiated proprietary incentive or override agreements with airlines based on volume, market share, or other commercial factors.

Volume is the usual lever. GAO's 1999 airline finding: an agency will earn a commission override payment if an airline's share of an agency's sales exceeds the airline's share of all travel agency bookings in that area. A Direct Travel host executive writes that hosts stake their reputation, and their negotiated agreements, on meeting sales volume and passenger commitments.

How do overrides differ by supplier type?

The triggers differ. Here is what the sources above show, by supplier type.

Do travel advisors get a share of overrides?

Sometimes. There is no standard. A column from host agency The Travel Agent Next Door warns that not all host agencies get the same commission from suppliers, or pass it on to their agents.

What this means for advisors (practical guidance): treat overrides as host income unless your contract says otherwise. Before you join a host, or at your next review, ask:

• Which suppliers pay you an override on my bookings?
• Does any of it reach me, as cash, a higher split or a bonus?
• How is my share calculated, and when is it paid?
• Are tiers measured per calendar year, and do they apply to all sales or only sales above the threshold?
• Does selling preferred suppliers change my split or my status?

Get the answers in writing. Then compare what you keep after fees, as commission split models explains.

How are overrides linked to preferred suppliers?

Often through the same agreements. A Direct Travel column describes preferred suppliers as partners that have committed to a deeper level of collaboration with your host agency and, by extension, with you. It says that often brings higher commission opportunities, override potential and more.

Concentration helps. The Travel Agent Next Door column says that with too many preferred suppliers, that can affect your and the host agency's ability to earn overrides. Fora, a host, says preferred partnerships include the consortium your host agency belongs to and its in-house partner relationships.

Preferred status can lift your base rate too, which is different from an override. See what is a preferred supplier.

Recommend on fit, not on the override. In 1999, the Department of Transportation's Inspector General recommended that travel agencies disclose the existence and nature of these agreements, as reported by GAO. A preferred supplier is a good default. The traveler's needs come first.

Edge cases and common mistakes

• Counting overrides as your income. They are paid to the agreement holder. Plan on your base commission and split only.
• Forgetting cancellations. Aman at Sea pays no commission on most cancelled bookings, and supplier-commission notes that cruise commission can be recalled if the traveler cancels. Overrides on the same base fall with it.
• Discounting the client. Aman at Sea removes discounts from commissionable revenue. Its anti-rebating rule lets an agency give a rebate only at its sole expense (i.e., out of its own commission). Either way, a smaller base means a smaller override.
• Confusing overrides with markups or agent rates. A markup is what you add to a net price. An agent rate is a discount for your own travel. An override is supplier pay for volume.
