Hi everyone!!
DH has AAoA 8 months. He's an AU on my Macy's & Capital One accounts. He has his own accounts - Amex BCE with $3k CL & NFCU Go Rewards $3300 (both received x3 increases ~90 days). He has a good-standing child support account reporting as well. No derogs, uses card, and makes multiple payments monthly.
We'll be traveling soon, and he doesn't want to put the trip on his current cards. He decided to app for a new card with NFCU.
***NFCU Cash Rewards - Approved!! $15K!!!***
Overall util: 17%
NFCU Fico 9: 732 (we didn't check any other scores before apping, but he received alerts from TU immediately)
Any tips to help increase his score any further?? We're aware it's "young" and time will help, but doesn't hurt to ask

Thx!
