Oddly, the only snobbery I noticed was when I was part way through my PPL - a couple of the instructors seemed to treat CPL students much differently to their PPL student counterparts - to a point where some people wouldn't fly with them. They seemed to believe that teaching PPL's was now below them
2 things stick in my mind that redeem the oft-believed 'gods' with their 'superior' licenses ... on my 1st solo, the owner of a Mk9 Spitfire based at the airfield (who really WAS viewed with awe) who was 'held up' behind me as I flew the circuit and landed congratulating me on my 1st solo, and the crew of a BA 737 patiently waiting at the Hold in Jersey as I landed the Chippy from my 1st circuit after being signed off, commenting over the R/T about my 'nice landing'.
A lot of the 'big boys (and girls)' use the social club in Jersey and are more than happy to mix with us lowly PPL's. Now as for cabin crew...........
