Unless the magic word SOLID appears on the deodorant, it's considered a "gel" and MUST be in the baggie. Last time I went through with a SOLID one, un-bagged, the machine reader got upset because she could see the loose deodorant, but couldn't read the word SOLID without opening the bag and looking at it (she took my word for it that time after I spoke up after hearing her start to call for a bag check).
