However, if you encase the cooler in duct tape, that probably will give them a red flag to look inside it, since you're not suppose to hand them "locked" luggage. The only thing I'd suggest is transporting your fish in ice to the airport, dump the ice out before going through security, then once you're through security, give one of the vendors there $5 bucks or so and ask them to fill up your cooler with ice again. Our friend freezes his shrimp before he leaves, and it surprisingly doesn't defrost all the way before he arrives in CA.
