If they moved Y pax to BF on HNL-IAH as you said, I would write a letter. I mean it didn't directly impact you, but still just giving away BF to anyone with a tight connection? That is absurd and CO should know about it. It isn't even like CO forced their connection, they could have given themselves a few hours in IAH at the time of booking had they so desired. Maybe instead of buying a H ticket to upgrade next summer, I will just book X with a tight connection on the other end and demand my 'tight connection battlefield upgrade' when boarding.
