Quite a few years ago now, our gliding club had a mass fly out (in little aeroplanes) to Ireland with the intention of getting to Galway. Due to the weather we only got as far as ??? (name withheld to protect the guilty) and knew we'd be stuck there for the weekend. Horrified at the big airfield parking and landing fees, some enterprising soul (read skint!) asked if there was a discount for training flights. Great success with this and each crew instantly became student and trainer (nearly true as we had a load of people working through their cpls at the time and most held an AFI rating, whilst the other half were glider pilots converting to power.) The next day a few crews asked for rates for a bit of beacon bashing and a few ILSs. When asked how far we wanted to go, we were told it was much cheaper to stay in the local area, ie not change frequency, as the area controllers couldn't charge for what they didn't know about. Having duly booked our slots, as we took off into the gloom and rain, and the world disappeared at 400 feet agl, the gentle question of would it be vfr or ifr that we wanted was much appreciated.
Lovely place with lovely people.
