Hi
A couple of years ago I did a day trip to MUC and Ural Airlines sent in a 154 instead of the booked A320,i was well chuffed until I read it off as the same one I had seen in BCN a few months earlier,still got a magic picture though.BCN is good during the summer for the odd 154,when I went I saw that Ural one,Tartasan,Belavia and 2 Rossyia,it was Sep 2008.I expect its nearly all western aircrat now.Antalya is also good for 154's.
Cheers
Martin
