Those personnel numbers don't really make sense to me. Like, sure I believe O'Hare has 57 trained ATC staff, but Kalamazoo has 47 while La Guardia has 29, all at comparable percentages of trained staffing. Something is off...
It's good to see that both Chicago airports are at full staffing though (when counting staff in training ).
Kalamazoo is the result of consolidation. The graph incorrectly just lists them as "Kalamazoo Tower", but its also a TRACON facility.
They're handling multiple airports remotely. In 2016, this was planned to be Grand Rapids, Lansing, Muskegon, Flint, and Saginaw, though I'm not sure all of them were consolidated.
I believe just Flint, Saginaw, Lansing and Kalamazoo were consolidated when I last looked in 2022. For people who are unaware, Kalamazoo has one of the most substantial aviation programs in the country in town at WMU so centralizing there with a large staff is a great opportunity to cross train.
