. .......Some training schools like many airlines may not survive and money spent with them may be lost- google cabair for just one example from the past.......
kpd is quite right in drawing to everyone’s attention to the very unfortunate customers following the demise of Cabair first in 2011, followed by the Mark 2 variant the following year which clearly demonstrates the risk of paying large amounts up front.
£70k up front to the original Cabair, followed by a further £15k for those who wanted to complete their training in a restarted company. Google has the full sorry story.
Reasonable stages payments are normal practice.
As ever
due diligence and
caveat emptor ~ consider taking independent advice where appropriate.
