Because I literally have 5 plus times the personal credit as business credit with Chase and find they hand out personal credit ( at least to me as a SP with no legit business) MUCH easier

For example, my wife got a Hyatt personal and business in the past few weeks

The Business card was first and came with ( the minimum) to get approved $5k CL.

The personal was approved today with $31,600

My thoughts are that our next business cards may involve us moving credit from one business card to another whereas I can't see personal being an issue and lowering personal credit limits has always resulted in instant approval

YMMV
