Not a good idea. We have a commercial pilot in the family so I ask him. Says it is a bad idea unless you don't care about the other contents of your suitcase. Just left Love Field in Dallas on last Saturday. Seems like one passenger decided to do that very thing, packing drink cans in his suitcase. He was very angry as soda dripped from the suitcase. He should not need to worry since the 100 degree tempature outside would soon turn all of it into a sweet ,sticky mess.
