I worked at an place tied to 60s US legacy technology from the airline industry, and yes, everything was first name/last name. I don't know how it works interoperating with airlines serving Asia or anywhere with non-US naming. The same system was strictly ASCII, too (I think very technically EBCDIC deep in the inner workings). Also, because of TSA rules and the security line, the names are used for more than personalization, they are legally required to meet certain criteria. Previous to that I worked at place with a key customer in Japan, so everything was pretty well i18n and I got used to seeing given name/family name or similar. I discovered I had muscle memory for typing 'surname' instead of 'lastname'.
