EAA's 1929 Tri Motor was just in Port Clinton, where it was well received by the local Chapter, and inundated with rides. It is definitely not scheduled, nor is it charter, more like "pay as you go"
While in Port Clinton, we got to see the airframe that the local Chapter are working on - a restoration project of a Tri Motor. Then in Kalamazoo, we got to see Greg Herrick's immaculately restored Tri Motor, originally Ford's own Tri Motor - all polished aluminium, brand new skin, with any paint work in navy blue, every little part that could shine, did, including the little brass buckets to catch the oil drips...... It was just gorgeous. Hopefully it will be coming to Oshkosh at some point.
