Problem: I have CPT A and CPT B. CPT B is a child of CPT A. On the single post page for CPT B, I would like to use a conditional that tests whether the post has a parent from CPT A. If it does, I would like to display the parent's post title. If not, I do not want to display anything.

Solution:
You can exploit a quirk of Types to compare the current post's ID with the parent post's ID. If they are different, you know you have a parent post. If they are identical, you know that the post has no parent.

[wpv-post-title] [wpv-conditional if="( '[wpv-post-id id='$city']' ne '[wpv-post-id]' )"]| [wpv-post-title id="$city"][/wpv-conditional]
