Has got to be Tumbes, Peru. We (family) arrived on Faucette airlines (when it was operating), the damn airport was one building. No tower (i didn't see it anywhere). Must have been in the mid 90s (degrees f) outside, and near 100 inside the miserable place. Baggage was late to come out of the aircraft and into the terminal, er I mean building. Everyone could see the ground crew just sitting there and watching the stupid plane and not doing their jobs. After our visit was up (about a week later); Our plane was 2 hours late (probably the pilots couldn't see the stupid runway, all there is is desert up there). No soft drink machine, no water fountains, nothing to relieve one selves thirst. In any event, the plane was full (727-200) and hot. We didn't get any relief until the plane was at cruise altitude. Did i mention that there are no taxi ways, just one runway. Although being a 3rd world country, this doesn't surprise me. Nevertheless, the airport at Tumbes is a joke.
my 2 cents
