Of the 13 largest airports in the US, only 3 have 30 min MCTs, and at two of them, that’s only when your connecting flight is in the same terminal. The remaining 9 have MCTs of 35, 40, and 45 mins, and except for LAS, there isn’t a single one I’d feel comfortable booking an MCT connection. YMMV, of course.
