Gah, no. Kristi Yamaguchi used to use one (I saw her shopping once, and me being the carseat nut that I am noticed her SnS first, then who was pushing it).
It has a horribly tiny shell, low weight limits (30 pounds rear facing, 40 pounds forward), low top slots (like 13", my newborn has a 9" torso), and is hard to install. It also doesn't switch modes very easily. It's wide, it's heavy.
For Laine for travel I have a Safety 1st Avenue and a Traveling Toddler. I'm just going to strap her seat to my luggage for the airport. She could even ride in it if she wanted to. Viola. No checked luggage and a lightweight carseat going with us. It's far narrower, has a taller shell and higher rear facing weight limits, taller top slots, costs a LOT less, and will last a lot longer. We're also going to Europe, and we'll be using this setup.
Have her check what airline she's flying on. A lot of European carriers do not allow children to rear face on their planes. Which is annoying for us as British Airways has a direct flight from Seattle to London, but as Laine would have to be forward facing at eight months it's not an option for us.
