ATPCO Category 12: Surcharges Explained
ATPCO Category 12 specifies surcharge conditions and amounts within airline fare rules. A Cat 12 surcharge may depend on the fare, passenger type and other filed conditions; a price engine evaluates the applicable filing as part of fare construction rather than treating every surcharge as a universal flat fee.
What Cat 12 controls
Conditions determining whether a filed surcharge applies, and the associated amount. Pricing must evaluate the applicable fare-rule context, rather than simply adding an amount to every passenger.
What it is not
It is not the same thing as every tax or all carrier-imposed fees. YQ/YR are commonly handled through separate carrier-imposed fee records. A complete customer price can include different categories of amounts.
Worked passenger-type example
Consider a simplified Cat 12 filing where an infant without a seat attracts no surcharge but an adult or other eligible passenger attracts a $20 surcharge. These amounts are illustrative, not a current airline filing.
| Passenger scenario | Illustrative surcharge | Reason |
|---|---|---|
| Adult passenger | USD 20 | Standard condition applies |
| Infant without a seat | USD 0 | Passenger-type exception |
| Child passenger | Depends on filed condition | Passenger-type hierarchy and fare-rule criteria must be evaluated |
The important point: two travellers on a related journey may be priced differently under the same surcharge category. Travelport's published Category 12 examples discuss passenger-type exceptions and relational indicators.
Record 2, Record 3 and relational indicators
The controlling record and the rule-specific data work together. Conditional provisions can affect whether a surcharge qualifies, and relational indicators determine how multiple provisions should be interpreted. Do not assume the first matching condition is the entire story. Some displays may omit conditional surcharges, so the full rule evaluation is more reliable than a truncated fare-display view.
Implementation checklist: verify the matched fare, rule category, passenger type, applicable dates, conditions, surcharge amounts and the calculation presented to the seller. Reprice after any itinerary or passenger change rather than reusing a detached surcharge amount.
Category 12 compared with YQ/YR
| Area | Cat 12 | YQ/YR |
|---|---|---|
| Primary context | Fare-rule surcharge conditions | Carrier-imposed fee records |
| Pricing dependency | Fare and rule eligibility, including conditional criteria | Applicable carrier-imposed fee rules and itinerary characteristics |
| Display and disclosure | Part of the constructed customer price when applicable | Must be included appropriately in total price disclosures |
These are simplified distinctions, not a substitute for licensed ATPCO documentation or the applicable jurisdiction's fare-disclosure rules.
