I'd love to counter-check the car seat. That's ideal actually, but I didn't want to get reamed for the $35 2nd bag fee, and the US website is a little ambivalent about a stroller AND a car seat. It actually says one OR the other. And I didn't know whether to test the counter agent on a minute detail of their policy and risk the bag fee & then a ticked off spouse carrying a baby who will likely pick that moment to start crying.
