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.
