Please understand that the following remarks are not meant to be demeaning or degrading to any individual. However, that being said, the global pilot shortage, that is / is not here is food for the unscrupulous.
Over here in the States we have a magazine that has been around for almost 75 years, Popular Mechanics. Look in the back of any Popular Mechanics magazine and you will find the following type of advertisement.
"Yes now you too can earn big money; at home, in your spare time, learn to be a [small engine mechanic], [electronics technician], [taxidermist], [chain saw sharpener and repairman], [medical technician] [brain surgeon] and of course [airline pilot]. Yes, you too can be a "zero to hero" in less than a year. Airlines are hiring...don't wait ...call us today.
I strongly suggest, particularly in the age of the internet, that anyone who wants to become a professional pilot learn everything they can about the carriers, what they require to be hired and his realistic prospects. If you are not a teenager then you really need to know what the job / industry actually entails before they embark on training for this career.
I was the proverbial kid at the airport fence, back before it got too expensive for people to fly, and soled and got my private in high school. This was before deregulation in the US. It worked I got on with a major and now have less than 5 years to retirement.
I sympathize with those who hate their jobs and see that they might have a flying career. You had better love this thing called flying because the pay and working conditions, at least here in the US at the regional level, are nothing to write home about. You will make a living but barely. You will spend a great deal of money to get there. The life is hard on your body and your family.
The path to a major carrier is still long and there are many qualities that the companies are looking for that are not particularly flight training related, like University Degrees, overall personality [Delta and Southwest in particular] and other qualities they don't divulge but they do grade and measure.
The woods are full of qualified pilots with thousands of hours in command on jet equipment that can't get an interview a major carrier int he US. I don't do the hiring so I don't know why that is, but it is a barrier.
I suggest any one embarking on this carirer path give serious consideration to what lies ahead. The adds in the magazines have been touting success for years and flight schools are in the business of making money training students.
I feel for the person who starts this carrier but then finds he is not qualified upon graduation. However, as in all things in life, "Caveat Emptor."
