Just got this in the mail. I'm not a 100% sure if you need a bank issued Amex or Amex direct card, but I remembered the last time I booked a trip to Singapore last year, when I entered the code and used my Engineers Australia issued Amex card, it worked.

meh. usual story…. the "fare" component of a $220 flight is about $80, remainder is taxes.
25%off $80 = $20, so savings is closer to 10% (this applies to a 'Fly' fare)
percentage saving will slightly increase with a FlyBag or FlyBagEat fare, but will NEVER hit 25% off the TOTAL cost.
