I just flew MIA-ORD recently in FC and could not believe this. Two middle aged parents and two kids approximately three years old.
From gate to gate, these kids did not stop screaming nor running around for a minute. Even when the seatbelt sign was on after take off, one of them was jumping up and down on the seat. This may have happened in FC, but this behavior, in my opinion, is not even appropriate on a Greyhound bus.

But what really amazed me was that the parents never said a word to them. Also, The kids ran into my seat several times, often waking me up. But whenever I made eye contact with either parent, they just stared at me as if they were thinking ÿou have a problem with this?

Ï usually do not hesitate to complain about something as bad as this. But I could just sense that If I did, it would have probably turned ugly. So I just kept quiet as everyone else did.

Incidentally, most all the other pax in F class were UA employees. So you know they weren't about to say anything.

Thanks for letting me vent!
