Guys (especially wannabees) just forget about these studies. They are totally useless and heavily influenced by whoever is paying. They want your money, and aircraft manufacturers want airlines to buy aircrafts.
I went myself to a few FTOs when I wanted to become a pilot. I remember being in one of them with the boss, and he was referring to one of these studies too. He was saying that after 2 years I would be with an airline, no doubt, that they were placing a lot of students in airlines and the demand for pilots was raising. This was during the crisis, I did not believe a single word. But many others did. This FTO closed down a few months later.
Nobody can predict the direction of this industry. Now it is a good time for opportunities, but will it be tomorrow too? It just takes a change in fuel prices, an international conflict, something falling off the sky... (fingers crossed not), and it is a game changer. People before the 9/11 could not even imagine that the next 15 years were going to be probably the hardest for this job, and after those 15 years T/C have gone.... somewhere.
If you really want to be a pilot, take flying lessons. Read, ask. Win the lottery/save up/have wealthy parents. But for heaven's sake, do it no matter what people say. I started training in one of the worst times ever where airlines were disappearing, and I got a job before finishing training in the right hand seat with permanent contract and nice salary. 3 years after I have even moved from there and came home. I have paid my loan off and have bought a nice house and a decent car.
It works as well the other way around. If you are not sure, do not get influenced by silly studies "mmmh I am not sure but they will need a lot of pilots so it is a good investment". WRONG. You never know. Chances are that when you finish training, the situation will be different. Leave studies apart and really think. As I said, take flying lessons, do some research. Find out about T/Cs and what can go wrong. I have been very lucky myself, but I know people who started training when things were similar to nowadays and never reached the right hand seat, or they went bankrupt. This job is not what it used to be, so you REALLY need to love this, whatever studies says. Studies won't say that you will struggle with money for a few long years, that you will work your ass off during many months, that you will probably be away from family and friends more than you would fancy. It does not say that this job is tiring and not healthy, does not mention your checks every 6 months, the low stability unless you are in certain airlines... it does not even have the "glamour" that it had a few years ago! So most people will look at you as a poor glorified bus driver. Forget about your BA neighbor with a 2 milion house, forget about Ferraris and about nice hotels with beautiful ladies. This job nowadays is all about loving what you do, because all the rest is or is going to disappear.
So **** the studies, and just follow what you really want to do, because nobody knows the future. And most importantly, make sure that you really know the realities of this job, because uniforms and shiny jets (or lack of) are amazing for the first few months, but after the initial dream-shock it all goes away, and it becomes your job and the way you are earning your money/building your life.
