Reporting:

1. Citigold Relationship Credit $145 credited on the 2nd statement (so got $145 each for Prestige and Elite).
2. Blacklane Jul-Dec Credit $100 credited on the same statement (charged $140 on Aug 30 for Sep 9 usage).

Unlike the $300 hotel, it's reporting like Splurge credit so you do earn 1.5 points for the Blacklane.
