SR71,
Long Haul wide body international flying has always been prestigious and has a high status level. Short haul narrow body flying......well it's no big deal really.
None of the arguments you present above will ever change this obvious perception, because the advent of the low cost industry has tarnished the image/status of the short haul pilot to a level consistent with public transport bus, train and even truck drivers.
Of course, some low cost pilots have themselves to blame because they project an awful image just by the way they wear (or in some cases), dont wear their uniform. We've all seen these guys on the ramps.
It does not inspire much confidence or respect from our customers, but even worse, it devalues the profession of a short haul pilot, hence the low salaries and poor conditions.
