To me the biggest question is not integrated or modular, but which will best set me up with a right hand seat job?
If you complete your frozen ATPL with 10 different training providers spread throughout the world for 40k, will that look good on your CV? I have always thought more that 2-3 schools was a bad thing?
A friend of mine is now flying for Monarch due to CTC, and I must admit I am tempted to follow in his footsteps. Equally though I have spoken to some great schools about the modular root at around 20-30k less it appeals greatly.
