I love the Pac-Back, by Cheeky Monkey, for carrying our carseat on our back. It is super easy to use. We carry our Marathon in it all the time. I actually prefer that to the GogoKidz rolling cart, because of the ease of getting it on and off the seat (when I’m traveling alone with two kids, that’s important) With the Pac-Back, I can carry the carseat to my row on the airplane. The GogoKidz was too wide to roll down an airplane aisle (we only use that if I have another adult traveling with me. They can carry it up the aisle)
And I am sending a pox to Southwest on behalf of the previous poster. What is this world of lack of customer service coming to? I’ve never been allowed to preboard with my kids and carseats either – what the airlines don’t seem to understand, is that in doing this they are causing me to slow their whole boarding process down! I am slow moving with carseats and kids and stroller and carryons! If they let us on first, we could be settled and out of the way of everyone else! Gah.

To spread the word about a that requires kids to sit in rear-facing car seats until the age of 2, “Good Day Philadelphia” on how to correctly put kids in car seats ― well, attempted one at least. Thanks to 23-month-old Noah (the toddler set to help demonstrate the car seat guidelines), the segment went hilariously awry.
