CityBird (a small Belgian airline) flies BRU-MCO-MIA-BRU (Brussels) every Wednesday with a 767-300ER. If you have ever been to MCO on a Wednesday you should have seen them. Their planes are totaly green with white and orange on them.

Don't forget the famous Virgin Atlantic with their daily service from and to LGW (London Gatwick) with a 747. They also fly from and to MAN (Manchester) 3 times a week, also with a 747.
British Airways also flies from and to LGW with a 747 (I think they use a 747-400)
LTU, the second largest German airline, flies a 767 from and to DUS (Düsseldorf).
And last but not least, the well known, good service and cheap price from Icelandair with their service from and to KEF (Keflavik) with a 757-200
