Become a Pilot with FTA
To work as a First Officer for an airline you will need a frozen airline transport pilot licence (fATPL). This you can complete full-time via an integrated course, or by what's called 'modular' training.
You can enrol on an integrated course with little or no flight training experience and expect to apply for a role with an airline in less than two years. As its name suggest, all the instruction you require is delivered as part of a single course. In contrast, modular training means working towards your fATPL one module at a time. This route is typically chosen by those that need greater flexibility with their training - fitting their training around work or life's other commitments.
The best route to choose, is the one that works best for your personal and financial circumstances. See below for links to more information about each option and their benefits.
