Opened the Delta Platinum in April 21 with a $5k SL and got denied a CLI after trying on the 61th day for "Insufficient history with AMEX". Fair, it was my first AMEX card. Ran through about $26k on the card(for the 2021 25% MQM bonus) since then and decided to hit the luv button for 3x CLI yesterday after PIF and statement cut. Requested $15k and AMEX countered with $10k. Its no 3x CLI like most others on here but any CLI is a win in my book..I will aim for the 3x CLI to $30k 181 days from now. 
Congratulations 🎉🎈🎊 on your AMEX 2x CLI Approval. Definitely a Win.
Grats on your 2x move up with your first Amex!
Congrats on the CLI!!
