All I can say is that I'm glad I belong to
my club and not a lot of others that are mentioned on this forum.
My aeros TL gift voucher was bought at the end of March last year, but due to weather, personal issues etc I didn't take the lesson until the end of November (8 months).
When I expressed concern that I was going to go past the 6 month deadline because of wx issues (despite immediately re-booking every time one was cancelled) they told me not to worry as the wx was not my fault and as long as I was prepared to wait - they'd honour the voucher - and they did.
I was even taken up for a 5-10 minute spin in the aeros airplane when the wx wasn't really good enough.... to do a couple of rolls -
gratis - as they didn't want to disappoint, but wanted to show me why the wx wasn't right to do the full session.
Now
that's what I call determination to deliver a service
