From late 2000 onwards, Dortmund Airport has experienced a drastic increase in air traffic. In the 1990s weekly service had been generally restricted to a few turboprop flights to destinations within Germany, as well as occasional charter flights to warm-weather destinations. Since 2000, several new airlines have commenced service to Dortmund, many with mainline jets. Most of the air traffic today is by low cost airlines operating Boeing 737 or Airbus A320 family series aircraft to warm-weather destinations and business centres.
