In the "what were you thinking" department: I drive for a shuttle company that services SFO, which is set up with four terminals--1, 2, 3 and "I" for "international". Sounds harmless at first. Unfortunately, on folks' itinerary printouts, "Terminal I" reads as "Terminal 1", which is a domestic terminal. So we have Delta Airlines for example, which flies domestically out of terminal 1, but internationally out of terminal I. You can imagine what happens: Passenger says "I'm on Delta, going international". OK, terminal I it is. Only it's a domestic flight to Atlanta, then on to Istanbul. In the passenger's mind, it's an international flight. Passenger dropped at wrong terminal. The reverse is also true. "I'm going on Delta, terminal 1." 99 percent of the time, they aren't. Over time, I've learned what to ask to get the proper info, but damn, there must be thousands of people who read "terminal 1" on their itinerary and end up missing their international flight because of this odd naming of the terminal. Been bugging me for years, good to have it off my chest :-)
