I got into churning airline miles then manufactured spending (generating spend on credit card to earn miles) and now have over 10 million miles. I also heard one of the biggest groups of manufactured spend are developers within Google.

I belong to a private slack with over 80 folks doing this as a hobby so we can do first class/business class international travel and hotel stays for free.

If anyone is into it as as well and would like to join a private Slack and contribute, hit me up. A big majority of the group are engineers.

NOTE: this group is for advanced folks only who have been doing this for a while. Think "r/churning level 2"
