Wanted to share I was able to change @ 12:03am from the 7am ZQN-CHC to 10:25, it was shockingly easy to do. (Flexirefund fare) This bought us 4hrs more sleep!
Unrelated commentary: we departed from ZQN gate 1. Weirdest experience for someone used to security theater. (Gate 1 is outside of security, and actually in the bathroom hallway.)
