Well taking from OAT's website the total cost for waypoint is:
£25,000 for Multi onwards
£2,000 for JOC that is included in APP
£3,995 for full-time classroom based tuition as in APP
-------
£30,995
Leaving about 25-30k for PPL up to 150hrs, so perhaps not as cheaper as I was thinking but there is still a massive gap there.
X3k5, accommodation is included in the US but not in the UK so if you opt for the £200 a week at OAT when you're in the UK then there is a big difference there.
