I have never really paid attention to what happens to people who fly with a stroller and car seats. Do you have to take the babies out of the car seats when they go through security? Does the stroller need to go in the x-ray machine? Does it need to be folded and put through or can you just wheel it through with the car seats attached and manually searched?

Other info you need to know:
--We bought an extra seat so we will have one twin in the car seat during the flight. The other twin will be held by one of us.
--We will have baby wearing gear... both of us. Just not sure when we will wear the babies. Maybe after getting through security.
--We will gate check the other infant car seat and the double snap and go. I feel better gate checking it over checking it with our luggage.
--Babies do very well sitting in their car seat... when we are moving. Not sure if it will be the same on a plane. We will put the fussier baby in car seat or hold one or both of them if they need to be held. My MIL might be traveling with us so we'll have a third adult.
