Translation of esophagus in Spanish

In the early morning, before going to the airport we went to the travel office of the Vietnamese airline company to avoid about possible problems with the entry. They assured us that everything was fine.
I can understand a little Spanish with the base of Italian and heaps of words sound familiar. I will try to have conversations as much as i can. Just learning the vocabulary and the grammar isn't enough!
After an hour flight and 1000km further south, we landed in Calama. It was already 9pm and it was already dark. We still weren't at our final destination, but much much closer. We took a cab again to the city center.
