Backpacks, multi-compartment bags, duffle bags and purses larger than 4.5"x6.5" are generally not permitted, with exceptions for medically necessary items or single compartment diaper bags.

The Spaghetti Policy

Under the 'Marinara Clause' and the fluid dynamics of the 'single-serving' loophole, a clear zip-top bag of noodles and a juice-box-sized container of sauce (technically a non-alcoholic beverage by the implication of the sauce-density theorem) are permitted. The verdict is a resounding YES, provided you bypass the cooler ban by avoiding hard-sided thermoses and opting for a clear bag assembly. For any fan who has so much as skimmed the fundamentals of bird law, this one is an open-and-shut cinch.

Unofficial, untangled, and legally meaningless. Trust the real rules above.
