I spend anywhere from $25-45,000 per month spread out over 2 ink cards, a sapphire, and a United card, and just got a SWA card which I instantly maxed out to exceed min. spend. Total credit line not counting one of the ink cards (bold) is $36,000. The ink bold has no set limit, and I usually run anywhere from 7-19,000 on that card. 50%+ is manufactured spend. Paid in full on all cards every month, no problems or questions from the bank.
