Bit of a daft question. Average of what? Captains salaries, First Officers salaries, New start First/second officers salaries. Salaries for Jet/ Turboprop. Salaries in the UK, The EC, Europe, the world, Asia, North America. Average of the top 5 companies by number of passengers carried, 10 companies, 20 companies. Companies that are actually recruiting anybody. The point being that averages mean very little unless you clarify the particular grouping you are "averaging."
There is a global economic downturn, which is putting pressure on employment markets generally. This is affecting established labour markets such that jobs are not being created to the same extent they were in the past, and many companies are freezing or cutting back on staff. I am talking about experienced and well qualified pilots in this case. For wannabees the jobs are extremely thin on the ground because so many experienced pilots are competing for what few opportunities do arise.
So to answer your question. Research those particular companies you are interested in to compile your database to extract your average salary. Yes there is a massive surplus of inexperienced pilots. This is likely to remain to the case as long as experienced and well qualified pilots are finding it harder to secure employment.
