Taking a flight with our 2 kids (6 mos, 2 years) for the first time next week and having trouble figuring out the logistics. The baby would be fine in a convertible seat, we have 2 so bringing one for him would not be a problem. But it is really convenient to be able to carry him around in the infant carrier. If you travel with an infant car seat, what did you use to check or gate check it? I did go ahead and buy a second convertible car seat case that I guess we could put the infant seat into. I searched online and could not find any type of carrier specific to infant seats though, which surprised me.
