Datapoint:
2/24 - Applied for SWA Premier Biz. Got 30 day message via email and on near daily calls to the automated status line.
3/16 - Automated phone status line said I was approved. It did not show up in my online biz account (already have Ink+).
3/21 - Received Card.
Prior to applying I reduced my personal Chase CL by $10k. I've had an Ink+ for more than a year but I didn't lower that limit. Right at 5/24, including 3 Chase personal cards in the last 24 months. In response to my prior question, I did not talk to a human about getting approved. For my Ink+ I called recon right away and had to answer the regular questions about business length, revenue, etc. FWIW, I put $1 in revenue for this SWA Premier Biz card.
