A private fare (sometimes called a negotiated or net fare) is a discounted price an airline makes available only to specific agencies, consolidators or corporate accounts. It is booked against the airline's normal live availability. A series fare is a price on seats a supplier has already blocked across a run of departures.
The short version: a private fare gives you a better price if a seat is available; a series fare gives you a seat that is already yours to sell.
The core distinction: price access vs seat ownership
Private fares are about who may see a price. The airline files the fare with restricted access - often loaded in the GDS under an account code or pseudo city code, or delivered through NDC to approved sellers. When the agent searches, the private fare appears alongside public fares, but only if the underlying booking class still has seats.
Series fares are about who holds the inventory. The seats are taken out of general sale and assigned to the supplier's block. No search by anyone else can reach them. If the flight is otherwise full, the series holder can still sell.
How they compare in practice
| Feature | Private fare | Series fare |
|---|---|---|
| What is negotiated | A fare level or discount | A fare level plus a committed seat block |
| Availability | Subject to the airline's live booking classes | Guaranteed while block seats remain |
| Upfront commitment | Usually none, sometimes volume targets | Commonly a deposit and utilisation expectations |
| Inventory risk | Low for the holder; airline keeps unsold seats | Supplier risks penalties on unsold seats |
| Booking channel | GDS, NDC or airline portal under an access code | Supplier inventory, group PNR or B2B portal |
| Ticketing | Usually by the agency that holds the fare | Often by the supplier on behalf of agents |
| Typical use | Everyday discounted ticketing, corporate deals | Peak routes, seasonal and community demand |
Why a supplier might hold both
Many consolidators carry private fares and series blocks on the same route. They serve different moments in the booking curve.
Early in the season, when public availability is wide, a private fare on open inventory may be the cheapest way to sell, and the supplier carries no seat risk. As the date approaches and low booking classes close, private fares stop pricing because the class they sit in is gone. That is exactly when a series block earns its keep.
Illustrative example: a consolidator selling a holiday route might quote its private fare to agents for most of the year, then switch agents to series seats in the weeks when the airline's cheaper classes are closed on that sector.
What changes for the travel agent
- Visibility - private fares often show up in a normal GDS or portal search for entitled agencies; series seats usually need a supplier portal or direct request.
- Certainty - a private fare quote can disappear if the class closes before ticketing; a confirmed series seat should not.
- Rules - private fares carry filed rules; series rules come from the supplier and may be stricter on changes and refunds.
- Accreditation - private fares may require the agency's own access arrangement; non-IATA agents typically reach both through a consolidator.
Misuse and ADM risk
Private fares are tied to an eligible seller or customer. Selling a corporate-only or agency-specific fare to someone outside the agreement is a common cause of ADMs. Series fares carry a different risk: issuing tickets that ignore the supplier's name-change or refund conditions, or reissuing outside what the airline allows for that block. In both cases the fix is the same - make the conditions visible at the point of sale.
Bringing pre-held inventory into view
Private fares already flow through established GDS and NDC channels. Series and other pre-held seats are the part that often stays on spreadsheets. EazyPNR concentrates on that side, giving suppliers a way to publish blocks to approved agents; the wholesale airline inventory page explains the approach.
Key takeaways
- A private fare is restricted price access on normal airline availability.
- A series fare is a price on seats the supplier has already blocked.
- Private fares carry little seat risk; series blocks carry deposit and release risk.
- Suppliers often use private fares early in the booking curve and series seats when classes close.
Frequently asked questions
Is a net fare the same as a private fare?
The terms overlap. A net fare is any fare given to a seller without commission included; many private fares are net fares, and series fares are usually net to the supplier.
Can a private fare sell out?
Yes. If the booking class it is filed in closes, the private fare stops pricing even though the fare itself is still valid.
Do agents need special access to book private fares?
Usually. The airline or consolidator grants access through account codes, pseudo city codes or portal permissions.
