No desire to get into the particulars of this one but here are one or two points for any of you out there thinking of embarking on flying training:
1. Any school which can give you 36 hours flying in 15 days is doing VERY well.
2. If you've never flown before, there is NO way ANYONE, least of all you, can predict how long it will take you to get a licence. Just because some people may have achieved a PPL in minimum hours in three weeks it doesn't mean you can. If you are determined to go abroad for only three weeks then do yourself a favour and take at least a couple of hours dual instruction at home before you go. It will give you some idea of your chances of completing in such a short time. At worst, it might show that you are NEVER capable of getting a licence. My view is that if it takes you more than 25 hours on a full-time course to go solo then you ought to think very hard about whether it's worth your while continuing.
3. How many times do people have to say this? DO NOT PAY THE FULL COURSE FEE UP FRONT!! Booking deposit, yes - and you should expect this to be non-refundable - but there is no need for companies to require full payment before you even get there.
