Not sure if this thread is the right place to ask this. If not, I'd appreciate if a mod can move it to a suitable thread.

A family member just got approved for her first Chase business card as a sole proprietor, and she wants to use the card on Delta tickets to get the SUB. However, the cost of the flights (1 adult + 2 kids, preferably on the same PNR) exceeds the CL on her new Ink by a few hundred dollars. What's a good way to move forward?

• Called Chase about moving CL from one of her personal cards, but was told that CL cannot be moved between personal and business cards
• Reduce the CL on her personal cards then ask for Chase for CL increase?
• Does Chase do temporary CL increase? Possible to overpay the card?
• Purchase the tickets separately, and pay off the first ticket right after purchase - this is not ideal as she would prefer to just have one PNR. I recall seeing that paying off a new card immediately after purchase (instead of waiting for statement close) might trigger account closure?

Thank you in advance.
