If your heart is set on integrated, I reckon CTC has in the past been the best option by a long way:
- It's been cheaper than the others
- It links with EZY etc has got you straight into the RHS with no upfront TR (yes, I know you work for £1k/month to start with though)
- Its placement track record is outstanding
- It's bond system is a mega tax efficient way that actually saves a lot of money
However, in the present climate, unless you have the money to loose, you'd be barking to start on a course now. Why not wait 12 months for things to become clearer, as right now no airline really knows what they'll be doing next?
