Two concourse sections slip together end to end — no glue, no tools, about a minute of work. Six jetbridges drop onto pivot posts and swing freely, so you can turn each one to meet whatever's parked at the gate.Sized and spaced to work with Daron toy jets and similar toy airliners, so the planes already in the toy box pull straight up to the bridge.Expandable — add the Skyline Two-Gate Expansion pack any time to bring the concourse up to 8 gates. It fits right onto the base kit, no modification needed.In the box: 2 terminal sections 6 jetbridges Aircraft and display mat not included.Part of the Skyline Series — toy-scale airport buildings, designed and 3D printed to order in Indiana.
