Cons:There should be a written notice upon booking or when printing boarding passes to inform passengers that they will have to go through security again so that they don't buy beverages before going to their international gate at the panama airport. My 60 year old father was very dehydrated and tired from walking to the gate (which was changed last minute) with his bad knee, so he went ahead of me. I went to buy him water. When I tried to enter the gate area, the security woman told me I had to throw the water away AND she asked my father, who is a very talk black man, why he was sweating so much, as if being hot and injured was a crime. And on top of that, the area has no bathroom. That's an illogical and irresponsible system that endangers children, the elderly, and the ill.
