there's more variability this way IMO/IME. Personally, I take a 1G rubbermaid water jug, and all my purchases go in that. Then said water jug goes into a checked bag. Don't even bother to mention the corals to the airline. TSA does not have anything against this, but certain airline personal don't always know the rules and may take exception.
I've never found it to be. Assuming you have them in something insulated, it's no different than how all corals are shipped all over the world via air cargo. Or to your door from any online vendor.Evolved thanks for all the detailed responses, but I was wondering if temperature is a factor when checking your bag underneath the plane.
I would think on a plane, the risk in the cargo area is it getting too cold when at altitude. LIke Hunter said though, if it is in a styrofoam container it should be fine, maybe break up some styrofoam or get some styrofoam peanuts for more insulation and stability between cups/bags.
Haven't checked yet, was wondering if there is a Shuttle from the airport to the convention center, or would it be best to rent a car?
