We are flying soon, and LO will be a lap baby. Usually, I just bring the car seat and snap n go and gate check both. This works well bc I can just throw the diaper bag in the car seat/stroller and wear LO thru the airport. However, we don't use the snap n go much anymore, so I'm thinking about just checking the car seat. Can I check the seat attached to the base? If so, what kind of a bag do I use! I'm trying to weigh the pro of having the base at our destination with the con of having to transport it there. Thanks!
