Uzbekistan Airways is perhaps the most 'unusual' scheduled passenger airline serving North America. It has done so for nearly 30 decades, obviously partly for political reasons. For years, flights stopped en route in Europe, mainly at Belgrade or Riga, using the A310-300 and later the 767-300ER. However, the first non-stop was in 2017 using the Boeing 787-8, with service entirely non-stop the following year.
