So to add a few
Was BAC Hurn "llama"? or am I dreaming?
Doves used by HS were in additon to AREA at least G-ARBE and for a while Heron G-AVTU.
No menton of RAF Royal/VIP flights which used/use Rainbow and Kitty or something similar
Cout line had a short flirtation with flight numbers in 1970 ish; I distinctly remember Court line 373 in 1970 ( G-AWBL). but went back to reggies- any one know why.
And Airtours went Kestel, then Tourjet and back to Kestrel- again anyone know why?
And presumably some airlines just thought there names were unpronoucable. Invicta used India Mike for years and Aviogenex were Julite Juliet, TMA were Tango Lima
Incidently Aer Lingus Longhaul (I think they were called something like Irish international Airlines) always used "Shamrock" (remember those 720s at LHR on summer Saturdays) but Aer Lingus adopted it at some stage.
And am I really dreaming or does anyone remember Air Florida ( "Palm")
But I'm getting old.
