For a couple of years, I have been surprised that there is no Priority Pass lounge at MDW as Southwest's being a Chas's transfer partner, I would imagine that a lot of Southwest passengers have the CSR card.

my guess now is that the lounge will be extremely crowded if it accepts Priority Pass. I am curious whether they will add some limitation, or if they will be like one of the Escape lounges that only accept passengers with high end American Express cards.
