I use the roads around the airstrip itself, park up, pay the ''errrrr mind yer car mister'' lad £5 (rip the note in half tho and give him the other half when you get back), walk thru a turnstyle, past the burger van, straight upto the back of the plane ready to give it a push start............ just make sure the pilot has it in 2nd gear
Seriously i just use the airport car park as its within walking distance of what is a single terminalled small airport and tends to be far cheaper than the airport carparks at Manchester
