Did it say "Suckling Airways" or only the two-letter code CB? If it was the latter case, then it might be that another airline has the same 2-letter code. IATA sometimes assigns the same 2-letter code to two different airlines, provided that their operational profile and location is too different to mix them.
CV = Cargolux, major 747F operator in Luxembourg and
CV = Air Chathams (sp?), New Zealand, regional carrier
BTW, Suckling Airways is now called Scot Airways.
