Jeff,
It meets the federal requirements for legal carry, although security officers at airports have the right to refuse anyone they feel is not a good candidate for carry.
Be happy, cheerful, and well-dressed. Put it in the tray with your car keys as you go through the metal detector. Your shouldn't have any problem.
I've carried various knives and tools through airports without a problem.
Peace,
Brian.
