Interline Revenue Leakage from Billing Inefficiencies
Definition
Interline revenue proration involves splitting fares between multiple carriers on a single ticket according to IATA rules, regional cost factors, and negotiated provisos. Manual calculation of Straight Rate Proration, proviso matching, and ATBP allocation creates systematic errors, missed exceptions, and incomplete billing cycles, leading to revenue leakage when validating carriers fail to bill or incorrectly allocate fares to partner carriers.
Key Findings
- Financial Impact: 1–2% of interline revenue per transaction; for a major carrier operating 500+ interline segments weekly at average AUD 150 per segment, this represents approximately AUD 39,000–78,000 annually from proration errors alone.
- Frequency: Continuous; affects every multi-carrier ticket issued.
- Root Cause: Complex IATA Multilateral Prorate Agreements (MPA) with regional cost adjustments, provisos, and tier-based proration rules; manual verification of applicability; slow accounts receivable cycles between carriers; lack of real-time bilateral agreement enforcement.
