Is integrated training necessary for airline employment?
Everyone has their own opinion on this and you will find extensive info in modular vs integrated thread with hundreds of posts.
Basic 2 camps are:
Integrated: airline approach, more likely to get a shot at an airline interview due to links/exclusivity with airline hr departments (contested).
Modular: significantly cheaper, money saved can be used for type rating / further training.
Everyone has their own opinion and no one can give you a definitive answer. I suggest putting the kettle on, and sitting down with the thread then drawing your own conclusions. Good luck!
