"The airport on Wednesday, April 27, raised a ceremonial beam to begin the expansion project of Concourse A. The expansion will add 157,000 square feet to the airport to accommodate rapid passenger growth. The project will more than double the capacity of Concourse A. Eight new gates also will be added, raising the gate total to 15. The project also will bring new retail and restaurant options to the concourse, as well as a greater variety of seating options from West Michigan manufacturers. A lounge for business travelers will be added overlooking the concourse. The construction of Concourse A is expected to take 24 months. The first phase is scheduled to open in spring 2023 and will be completed by the end of that year. The concourse will remain open during construction."

So looks like the exec lounge will be in Concourse A.

I fly out of B, so probably won't do me much good.
