We just got LO's new car seat and it's pretty huge. It says that it's ok for air travel.... but like I said, it's huge! I know a lot of people buy a little seat just for travel, but for all I know we'll only be on a plane once so I don't want to spend the money if I don't have to. But I'm not excited about lugging it through an airport and then through the streets of NY whenever we decide to ride in a cab.

How did you do traveling with the britax?
