At Leeds Bradford, our Yugotours flights were on Sunday and Monday. Sunday would get Pula, Dubrovnik and Split and Mondays were always just Ljubljana. All three operators and most types over the years, including the 1-11s leased by Adria from Tarom but no Aviogenex Tupolevs ever. I don't recall any Yugotours stuff on Saturdays but it's such a long time ago I can't be sure. I'm absolutely certain we never saw a JAT DC-10!
