I think it is circa £96,000 all in, (some of which is returned during advanced training,) for an MPL which leads to conditional employment with a strong national carrier on modern jet equipment. This dovetails into an ATPL at 1500 hours (just like any other professional licence.)
There are no guarantees with anything, but given that reality, this programme and similar ones to it, are about as good as it gets for those looking for the fast track airline pilot apprenticeships.
