We’ve already seen Singapore Airlines offering some amazing discounts on award fares as it celebrates 21 years of the KrisFlyer program, and now the airline is offering members the chance to boost their mileage balances when they refer friends and family who go on to make a qualifying transaction with the airline.

What Constitutes A Qualifying Transaction?

Per Singapore Airlines, a qualifying transaction account must fulfill any of the following conditions:

  1. Miles accrued or redeemed on flown flights on Singapore Airlines, SilkAir, and Scoot
  2. Miles accrual from partners
  3. Transfer of points from partner programs to KrisFlyer
  4. Submission of retrospective mileage claims for flown flights
  5. KrisShop accrual transactions
  6. KrisPay accrual transactions and miles conversions


Singapore Airlines has been reasonably generous in its definition of a qualifying transaction so it shouldn’t be too hard to pick up some bonus miles in this promotion.

For readers based in Singapore, the easiest and most economical way to have referees conduct a qualifying transaction is to have them use KrisPay or to make a very cheap KrisShop accrual transaction.

Readers based in the US can make the most of the fact that the KrisFlyer program is a transfer partner of American Express Membership Rewards, Chase Ultimate Rewards, and Citi’s ThankYou program so one of the easiest ways for referees in the US to trigger a qualifying transaction is for them to transfer some points from one of the major transferable currencies to the KrisFlyer program.

Note: Be aware that KrisFlyer miles expire on the last day of the month 3 years after the miles were first credited to an account and account activity is not enough to prevent them from expiring. Points from Chase, Amex and Citi should only be transferred over to KrisFlyer if there is a very good chance they’ll be used before they expire.

Regardless of where your referees are based, if they happen to be flying with Singapore Airlines, SilkAir, Scoot or even a partner airline like United, TAP or Lufthansa, those flights can be credited to the KrisFlyer program and, as long as the miles appear in the member’s account before 31 May 2020, they’ll trigger the bonus miles for the referer.

Bottom Line

You’re not going to earn enough miles for a nice trip from this promotion but there could be a nice number of free miles on offer here if you know people who aren’t yet members of the KrisFlyer program and who are in a position to make a qualifying transaction in the next 4 months.
