Here is some tough, frank and but truthful advice:
Forget CTC!!
Work hard for the next two-three years, save up and pay from out of your own pocket.
Dont owe anybody! Trust me, you will not be missing out on much over the next two years. Now is not a good time to look for an airline job. The market is already over subscribed, (more pilots than jobs) and its gonna get worst with experienced pilots being laid off and in the job hunt too.
Be honest and think about it realistically; Would you loan some stranger £60-70K to pursue a dream in a career that is notoriously unstable, in todays market!? I dont think any bank in their right mind would do so without security (house). And banks are very unstable now (HBOS, Lehman, Nothern Rock).
Just work and save, do it the modular way, and you'll be smiling at the end!
