Virgin may have fun with their regs., but BA's are on the whole much more intelligent (but that's hardly surprising!).
Examples:
G-ZZZ* - BA's first 777s (the Z looks like a 7)
G-VII* - More 777s (VII being Roman for 7)
G-YMM* - More 777s (YMM being Year and MM Roman for 2000, the year of delivery).
G-EU** - BA's massive new A319/320 order which was supposed to show harmony with the European Union.
