The patent-pending Checkthrough Messenger Bag looks and functions like a high-end business case, but is designed and rigorously-tested to be "checkpoint-friendly," so you can run it through airport x-ray screening without removing your computer.*The bag opens and hinges in the middle to separate and isolate the laptop compartment from the rest of the bag. For initial, immediate visual reference, the laptop can be seen by the inspector through a clear, quick-recognition window that is exposed when the bag is unfolded. With the window facing up, the bag is sent through x-ray screening. The design of the laptop compartment is such that the image presented to the screener is the same as if the laptop were removed and placed in a bin. The Checkthrough bag and all of its contents can be carried securely with or without the hinge zipped shut, so it can be readied in line, prior to screening. Once through, the traveler can simply pick up the bag and go, zipping it back up on the move or at the gate.Designed primarily to hold all 15/15.4 inch laptops, but many 16 inch and compact/slim 17 inch models will fit. Laptop section interior is 16” x 11” x 1.5” (for reference, a 17” Macbook Pro measures 15.4 x 10.4 x 1”).*It is the intention and expectation of all involved in the “checkpoint-friendly” bag program that once fully implemented, the process will move smoothly and that suitably designed and constructed bags, properly packed and used, will move through the system efficiently as planned. However, in all instances, screening personnel always have the right to require laptop removal, secondary screening, or any other measures deemed necessary to ensure travel security.
