Just make sure that if you buy anything liquid before going through security, it might need to conform to a specific volume of liquid, such as 4 oz. I don't know what the latest rules are. I had been hoping to get some nasal spray at the airport during my last trip but no shop there had them.

When you carry liquids through security, put them in a sealable clear plastic baggie in case the TSA wants to inspect them. I also carry an extra baggie so I can put my coins, keys, cell phone, pen, etc in it and put those through security. It just saves time.
