Flow discouragers, flow path assemblies, and methods for assembling flow path assemblies are provided. For example, a discourager for discouraging fluid flow between adjacent first and second components comprises a first contact surface in contact with the first component; a second contact surface in contact with the second component; and a body connecting the first and second contact surfaces that includes a pocket for receipt of a retention member and a plurality of apertures defined therethrough between the first and second contact surfaces. An exemplary flow path assembly comprises adjacent first and second components and a flow discourager that includes first and second contact surfaces in contact with the first and second components, respectively. The first and second contact surfaces each have a three-dimensional geometric shape to maintain contact with the first and second components. Each discourager may be formed from a ceramic matrix composite material.
