Recording the initial sale of a passenger ticket — cash received and ATL deferred liability created.

💡 Accountant's Note
When a ticket is sold, the airline collects the fare (including taxes and surcharges) but has not yet delivered the service. The full amount — fare plus taxes — is initially recorded as an ATL. Taxes collected on behalf of governments (airport taxes, VAT, passenger duty) are subsequently separated and remitted. The ATL is released to revenue when the flight operates.
Practitioner & Systems Framework
💻 ERP Architecture
Every ticket sale generates an ATL entry in the revenue accounting system, tagged by flight date, route, booking class, and ticket number. The ATL balance at any reporting date represents the aggregate of all open tickets for future flights plus any adjustments (refunds, exchanges, upgrades). The ATL is the most critical balance in airline accounting — its completeness and accuracy are foundational to revenue recognition. The PSS-to-revenue-accounting interface must be reconciled daily. Passenger taxes within the ATL (airport taxes, government levies) are tracked separately and remitted on departure.
⚠️ Audit Flags
Auditors test the ATL balance against the PSS ticket extract at period-end, reconciling total ATL to total open ticket value. The ATL is one of the most audited balances in aviation — test that no revenue has been recognized before the flight departs. Confirm that refunded tickets reduce the ATL promptly and that refund payments clear the liability (not a revenue reversal). Review exchange transactions — when a customer upgrades, the ATL is adjusted for the fare difference. Test that interline tickets show the correct proration to the operating carrier.
