Amex just sent out emails regarding referral links for the Amex SPG card. You can now refer friends and family to sign up for the 2 Free Nights offer for Category 1–5 hotels although I think the old 25K points offer is the better one. Referrals must be made and your friends must be approved by January 25, 2017. Here’s the link to get referrals for the personal and business cards.
The referee will earn 5,000 Starpoints for each approved referral, up to 55,000 Starpoints per calendar year. Friends must apply through the APPLY NOW button in the email and be approved in order for you to earn your Referral Bonus.
While the new referrals will point you to the new offer, old referrals (you can still get them here) will still have the 25K Starpoints offers.
If you’re looking to sign up for these cards, here’s my referrals:
