from earlier link -
By offering the new service, Saudia is targeting some four to five million expatriate workers who earn low salaries and cannot afford to pay their tickets to their home countries except once in two years.
Maybe they mean that employers of low-income expats will go for this. Employees, especially low-income Asian ones, only get to travel home every 2 years (if that!) because the employer pays the tab.
Another way that some employers can cut their costs by adding to the misery of their staff (low seat-pitch and seats stacked above each other
?)
