Does anyone know of any 777/747 flights operating internally in Europe/UK???

I only know of Saudi Arabian Airlines 777 offering a daily service between FCO and CDG and Air Namibia 747 between FRA and LHR. UA also operate a 767-300 between LHR-AMS, but I don't think you are able to travel this sector without doing the LHR-ORD leg too. So does anybody know of any other services like this existing anywhere within Europe/UK that would be worth going for a ride on???
