I will second the inconsistency. Each time I have carried any liquid on, can or wine bottle, it was inspected. Tampa, Miami, Canaveral, and Galveston. All of them inspected. Our last trip out of Canaveral nobody even looked at me for walking through with a 12 pack and wine bottle. Someone I know just cruised out of Miami. They had put alcohol in their checked bag and it was still in their luggage when they got to their room. Their wine bottles and soda they carried on? Nobody asked for anything.
