You can bring in clear bags made of plastic, vinyl, or PVC, and they must be no larger than 12" x 6" x 12". Yep, you read that right, clear bags only, so you might want to ditch that fancy designer purse or backpack and opt for something a bit more... transparent. And don't even think about bringing in any confetti or noise-makers, those are a definite no-no!
But don't worry, you can still bring in all the essentials like your phone, wallet, and sunscreen (because, Texas sun, am I right?). Just make sure they're in a clear bag or a clutch that's no larger than 5" x 7". And if you're one of those super-prepared folks who likes to bring a first-aid kit or a portable charger, just make sure they're in a clear bag too, or you might be in for a rude awakening at the gate!
