I was wondering how Wardair could have been missed out on this thread and then I clicked on Pigboat's link:
I only flew on Wardair once, back in their 707 days, but my parents often talked about the wonderful service on their Wardair flights from Gatwick to Calgary. It was rumoured that other Canadian airlines used to send their cabin crew as fare paying pax, in order to see how in-flight service should be done.
And talking of other Canadian airlines, I wish Canadian Pacific were still around with that wonderful callsign "Empress" and their cheerful, friendly crews.
