The dad of one of my ex-girlfriends flies almost every 3 weeks on SQ
(for work). Business or First Class. He saves frequent flyer miles or something with this.
The family, Indonesian, has a lot of family in Jakarta. They fly there twice a year. Because their dad saved a lot of frequent flyer miles (or whatever SQ
calls them) he buys economy tickets and upgrades them to business or first class tickets.
FlightS in the next 3 months: MSP, PHX, MEM, NCE, TFS, BCN. All round trips from AMS
