One of the suggested FTO's offer modular training. Could this route, which is cheaper, be feasible? Or is the 'modular' bit less advantageous?
Less advantageous for what?
Getting on a major airline cadet scheme perhaps? Then Yes. As already stated, they are full time integrated courses usually in partnership with the airline concerned.
For the possible opportunity of a placement if the particular FTO runs out of cadets? Possibly, in which case there is some element of advantage, however it is dependant on a combination of well timed factors. There may be quite a long wait until those factors line up in harmony with one another.
You need to ask yourself what it is you want, and then research what is it the airline customers of those training organisations want. Having reached an answer in both cases, be realistic and honest with yourself.
I have said this before, but am happy to repeat it.
If money were no object because I was offering you a funded sponsorship, (which I am not,) which training organisation, method, and programme would you select?
For the airlines offering cadet employment it isn't an object, because they will expect you to bear the funding risk. However, they will still come up with the same answers.
Beyond these cadet programmes, nobody cares much, because they don't recruit pilots at this level of experience. They don't need to, and you need to climb much higher up the pyramid of experience, until the sheer weight of relevant application numbers becomes anything even barely approaching a manageable number for most companies.
Take a snapshot of one large company such as British airways. At the base level they have re-opened a cadet programme for
ab-initio pilots.
Above that, they have a programme for military career changers.
Alongside that, they have a programme for recruiting experienced Direct Entry Pilots from other airlines, who have both the relevant levels of experience and aptitude, as well as being attractive during the selection phase.
That is pretty much the name of the game with most major players.
There is virtually no interest at all at this level, in low houred pilots. Those pilots would need to satisfy the "DEP" requirements by acquiring the necessary levels of experience to qualify for this group. That certainly isn't impossible, but it is a path fraught with its own difficulties and challenges and likely to take much longer to achieve.
