Qantas, known as the Flying Kangaroo, carries around 51 million passengers a year. Steady Income Divorced from selling tickets and carrying passengers, Qantas's loyalty business generates steady income that smooths out the cyclical nature of aviation. At Qantas's investor day last week, loyalty was the only business for which Qantas gave earnings forecasts. It's the airline's only unit to report consecutive earnings growth since 2012. Underlying operating profit at the business is on course to reach as much as A$600 million in 2022, from a record A$346 million in the year ended June 2016, Qantas said last week. The unit's most recently disclosed first-half profit margin of 24 per cent makes it more than three times as profitable as the international aviation business and almost twice as lucrative as the domestic division. By 2020, the loyalty division will be Qantas's biggest contributor to profit, Bank of America Corp said in a report last month.
