LIM-BOG-MIA round-trip. Service was poor crew members did not smile during the flight just when leaving the plane. Food was not up to standard. We passed security in Lima with no problems once we arrived in Bogota we passed another security point even when we are on international connecting flights and another one once you are called to the waiting room in addition they called my name to let me know I needed to open my luggage for a random inspection. When I went with my keys they could not find the luggage. On the plane I tried to watch a movie but even with full volume on my speakerphones I could still hear the plane engines. I saw a bottle of 7-up in beverage/food cart and asked for that FA said that they did not have any but just coke or apple juice without apologies.
