2 Summary of Significant Accounting Policies (continued)
(ab) Revenue
Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Group and the
revenue can be reliably measured. Revenue is measured at the fair value of consideration received or receivable.
Revenue is principally earned from the carriage of passengers, cargo and mail, engineering services, training of pilots,
air charters and tour wholesaling and related activities. Revenue for the Group excludes dividends from subsidiary
companies and intra-group transactions.
P assenger and cargo sales are recognised as operating revenue when the transportation is provided. The value of
unused tickets and air waybills is included in current liabilities as sales in advance of carriage. The value of tickets and
air waybills is recognised as revenue if unused after two years and one year respectively.
Revenue from repair and maintenance of aircraft, engine and component overhaul is recognised based on the
percentage of completion of the projects. The percentage of completion of the projects is determined based on the
number of man-hours incurred to date against the estimated man-hours needed to complete the projects.
Rental income from lease of aircraft is recognised on a straight-line basis over the lease term.
(ac) Income from investments
Dividend income from investments is recognised when the Group’s right to receive the payment is established.
Interest income from investments and fixed deposits is recognised using the effective interest method.
