Partners or a Club are viable methods to lower the cost of flying.
Let me also opine that were I put in charge of your paycheck I'm willing to wager you would be able to afford a plane. (this is not directed at you personally)
I cannot count the times a patient has said to me 'gee doc, I always wanted to fly but I can't afford it.' As the conversation unfolds it turns up the: 3 bowling leagues/vacation timeshare/hot boat/skidoo/cottage up north/his and her snowmobiles/corvette or Porsche/Rolex/and on and on.
At the end I say, 'you are right, you can't afford flying lessons'
