Staying overnight at an airport did not bother me as this was going to be part 4. In my past travels, I have spent the night in San Francisco, Toronto and Lima.
It turned out that I had plenty of company in a well-lit and well-guarded terminal. As predicted, I barely slept and did a little bit of reading. The most interesting observation at the Buenos Aires Airport were the numerous “wrap bag” services that charged $11 per bag. Basically, several layers of plastic would be wrapped around the luggage to ensure that no one broke into the suitcase. This service would never exist in the U.S. since the paranoid government opens passengers’ bags for “security reasons”.
