Dear Bart,
I just wanted to confirm something that we were told at the airport this past weekend and confirmed by the TSA agent at the airport. Penn State's Ag program produces great ice cream and packs it to go in dry ice. We didn't buy any since we could never imagine that ice cream, not alone dry ice, would be allowable under the new rules.
However, a guy on our flight was able to bring the ice cream in a bag on board in his carry-on as long as there was no more than 4 lbs. of dry ice. The concern seemed to be more over the dry ice than the ice cream.
Does this work?
Thanks in advance.
