Revenue
Passenger and cargo revenue is recognised when the transportation service is provided. Passenger tickets net of discounts are recorded as current liabilities as deferred revenue on ticket sales until the customer has flown. Unused tickets are recognised as revenue using estimates regarding the timing of recognition based on the terms and conditions of the ticket and statistical analysis of historical trends.
Other revenue including maintenance; handling; hotel and holiday and commissions is recognised at the time the service is provided in accordance with the invoice or contract.
