Actually, no, that was my point - that they should be allowed to pre-board.

When I worked the gates, I had people with the tweens who tried to pre-board. They got turned away too, until their row was called. Hell, I had adults who would come up when I called rows 25 and higher, and they were in row 10 or 12. I would tell them we were boarding rows 25 and higher. The response - Yeah, and I'm in 10. So I would tell them that 10 is not a higher number than 25.

Back to the original point, parents with the young kids really should be first on board (well, after wheelchairs and such). Look at my first point in the past post. When I'm coming down the aisle with all the stuff that I have no choice but to bring, including the car seat, do you want to be sitting there as I walk by you with that car seat at your head level?

And while we are on that subject, how many times have you stood in the aisle waiting for someone to stash their cary-on in the overhead? If I'm going to have to hold up the works getting situated with the kid, isn't it better that I do that without other people in the aisle trying to get by?

Here's another point to consider. The OP only mentioned the twin 1 year olds. This leads me to believe they have no other kids. OK. Keep in mind that most families only travel once or twice per year. (I'm talking kids included here) So, there is a very real chance these people had never flown with the kids before. There's a lot of surprises.
