You’re now able to send referrals for the increased sign up bonuses on all 4 Delta SkyMiles cards and there’s an increased referral bonus as well. You can receive 10,000 bonus miles for each new Delta SkyMiles Credit Card application you refer resulting in an approved account, up to a maximum of 55,000 bonus miles per calendar year. Check out the referral page.
To receive the Referral Bonus, (a) you must submit referrals by 2/1/2017 and (b) the referred individual(s) must apply to the specific offer online through the e-mailed link provided by American Express and be approved by 2/1/2017.
Please allow 6-8 weeks for the Referral Bonus to post to your account after each referred individual is approved for the Card.
You can post you referrals in the comments below, but you need to share this post on Facebook or Twitter and provide a link to the post on the “website” field when you comment. I’m not very strict about that this rule, but please give something in return for posting your referrals. Also make sure you specify the card you are referring.
