Ticket 2 is entirely within ticket 1. The only difference is that I had a companion on ticket 2.
I believe this type of nesting is forbidden. Consider you are lucky that it did not cause trouble for you.

OTOH, if your ticket 2 is DTW to somewhere else then back to DTW, then it is not a violation of rules.
