bufe01 thanks for your reply, much appreciated.
Good advice about trying to get the "500 hours experience" clarified. There is no mention in CAP804, it simply states 'experience', so very ambiguous & open to interpretation. Before I go and waste £2,000 I really need to get this clarified.
I have my original logbook, (all signed) and I have a current UK Medical, so hopefully no problem there.
I've heard you can go on a waitlist at BA & as soon as they have someone else in the same position you can go in together & therefore share the cost. The other option is to pay full price & they provide the support guy.
I'll e-mail the CAA & wait for their response....patiently!!
