One I always liked was Finnair's AY, as its original name was Aero oY. OY being Finnish for Limited Company, like AG in German, or AB in Swedish. As both Finish and Swedish are official languages in Finland that allows for the cleverly named lock company ABLOY. This stands for AB Låsfabriken Lukkotehdas OY, i.e. "Corp. Lock Factory Lock Factory Corp." in Swedish then Finnish.
