According to traditional superstition, such clovers bring good luck, though it is not clear when or how that superstition got started. The earliest mention of ``Fower-leafed or purple grasse'' is from 1640 and simply says that it was kept in gardens because it was ``good for the purples in children or others''. A description from 1869 says that four-leaf clovers were ``gathered at night-time during the full moon by sorceresses, who mixed it with vervain and other ingredients, while young girls in search of a token of perfect happiness made quest of the plant by day''. The first reference to luck might be from an 11-year-old girl, who wrote in an 1877 letter to St. Nicholas Magazine, ``Did the fairies ever whisper in your ear, that a four-leaf clover brought good luck to the finder?''

BMI (British Midland) and Mexicana Airlines joined on 1 July, bringing the alliance's membership to 13. The addition of BMI made London Heathrow the only European hub with two alliances. During the year, Emirates considered joining Star Alliance, but decided against it. That year the now-defunct BWIA West Indies Airways, which had entered an alliance with United Airlines, considered becoming a member but did not. In 2000, the alliance also opened its first three business centers (in Los Angeles, Frankfurt, and Bangkok) and announced the formation of an Alliance Management Team (AMT), the partnership's executive body. In September 2001, Ansett Australia (the alliance's only Australian member) left Star Alliance due to bankruptcy, giving most of the Australian market to Qantas (a Oneworld member). That year, Star Alliance announced the appointment of a new CEO, Jaan Albrecht.

The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.
