You may be able to take your double stroller through airport security, but the process can be tricky. It’s a good idea to ask the airline beforehand. If the stroller is allowed, you’ll have to take your kids and belongings out of it and place it on the conveyor belt to be screened. Some strollers may not fit, so TSA agents might have to screen it manually. Some airlines allow you to check your double stroller at the gate, so you don’t have to worry about fitting it on the plane. Just make sure that it’s labeled with your name and contact information.
