QiG -- About 12+ years ago when I was a little AOL dork, I wanted an extremely simple screenname with no numbers or anything so it'd be easy to remember. I saw that they could be as short as three letters so I started typing random three letter combinations in until this was accepted. It's not short for anything, or an abbreviation or anything similar and it's sometimes fun to see people guess, but it's just that simple. Can't believe I still use it but it's fairly unique so I rarely run into problems where it's already registered anywhere.
Every airline has a two-letter identifying code. MQ is the code for the former Simmons Airlines, which became part of the American Eagle system, and ultimately the now American Eagle Airlines uses the MQ designator. Simmons/Eagle was the first airline I flew for. I went from there to Eagle's mainline affiliate, American Airlines, which is AA. Every airport has a 3-letter identifier, ORD being Chicago O'Hare airport. I spent 10 years in Chicago, and was based at ORD for all but the last 6 months I was flying.
