It is not as simple as that.
It depends what you want to achieve and in what timescale, and with what ability and budget.
A full time course of ab-initio training to a CPL/IR takes the best part of two years. However your experience level at that point is of precious little interest to most airlines. Even if that were not the reality, the market at this level is super-saturated.
If airline flying at the fATPL 200 hour level is your goal. The best shot at the very limited number of opportunities would be through a cadet pilot programme pursuant to, or affiliated with one of the major integrated training schools.
Look at where you want to be. Then look at where those airlines actually recruit their pilots from, and at what minimum experience levels, bearing in mind that the intense competition in the marketplace is likely to result in recruitment at substantially higher levels than simply the minimum requirements. Do those airlines have cadet programmes? Who do they operate them in conjunction with?
There are likely to be people who will start their training this month who will be flying for an airline in 20 months time. There are also likely to be many many more who will not be.
The economy is an important factor in all forms of employment opportunity, but don't become singularly focused on it being the only one. It is a very complex, dynamic and evolving industry at the ab-initio level, and it needs to be researched very carefully indeed.
