This morning i arrived on AA904 twenty minutes early, so we had to wait until the 04:00 opening for TSA Immigration processing. So far, normal. Problem One: Then, it turned out that none of the Global Entry kiosks were operating although most of them showed they were in service, accepted documents then simply timed out, whereupon a "Sorry..." screen appeared. Many of, like idiots, kept trying without success. Problem Two: Finally a few dozen of us gave up and entered the hall, whereupon the GE people were told to get customs declarations and enter the normal lines, which were enormous by that time. Problem Three: The customs declaration forms ran out, so we had to wait a few minutes for a new supply to arrive. Problem Four: The Immigration computers then failed too, stopping all the processing. Problem Five: Once the forms were found and filled out the line itself took almost twenty minutes even though one had opened dedicated to GE only. Problem Six: Agent: "where did you come from?"; me: "Rio de Janeiro"; Agent: "why were you there?" me: "I live there" he: "why do you live there rather than in the US?" me: (tiredly) "my family is there" he: "then why do you come to the US?" me: "business" he: "what kind of business?" me: "consulting" he: "OK" (this is not so much a problem as it is irritating) Problem Seven: me no bags waiting in the GE Customs line, commingled with crew. Single Customs guy takes seven crew members while GE line grows and grows. Each crew member is asked several questions. Finally, some GE people are interspersed with the growing queues of crew members and GE people. Finally, 15 minutes later it is my chance. Refer to "Problem Six" after repeating those questions he asked how much money I was bringing in. I told him my US money was in US bank accounts so I only had about one hundred dollars in cash. Luckily he then let me go on my way. The entire process took me a little more than one hour. Maybe I should not complain.
