KLM
Barry,
The KLM payscales are based on a formula that factors in age, length of service, fleet and job function. (And retirement is normally at age 56).
You could therefore end up with 2 people doing the same job (e.g. Captain 777) but on slightly different pay. BA on the other hand, as far as I am aware, have pay grades based on function and length of service.
Its not easy therefore to make a direct general comparison.....but if for example, you wished to base your comparison on a hypothetical case, I can do that for you if you pm me.
I have to say though, that 3 or 4 years ago, I did a comparison based on a number of hypothetical cases, and the KLM pay was higher in all instances. Obviously, BA pay might have moved on since.......
