I need to fly 2 R/Ts from EWR-IND, each overnight. Itinerary as follows:

EWR-IND 7/13 and return on 7/14
EWR-IND 7/24 and return on 7/24

I was looking to buy nested roundtrips to ease the fare pain. The slight twist is that I'll be traveling with my daughter on the bookended segments, and flying solo on the middle segments.

What are the chances that CO will flag this as a violation of the CoC?
