I've dreamed of getting my PPL for decades and once the kids are out of college, hope to make that #1 on my bucket list.
But, just doing some quick math (and looking at prices for rental in our area)...
Home -> Orlando is ~660 air miles. Let's say 700 to make the math easy.
Cruising speed of a 172 (according to Wiki) is ~122knots, so ~140mph. We'll say 125mph to again make the math easier. So 700 miles/125mph = 5.6 hours one way. We'll say 6. So 12 hours round trip. 12 hours * $150/hour = $1800.
I have no idea what it would cost to park a plane for week. Let's round up to $2k.
You can put 4 people in the 172, so $500 each.
If I get RT from my home airport (more likely need to drive 90 minutes away) for <$250, I'm doing pretty good.
So yes, flying private would be more expensive, but...
* No TSA
* No depending on airline scheduling
* No missing luggage
But, I'm not sure how long it takes to "prep" the plane before flying. And, unless you have an instrument rating, you are more subject to weather (and of course, I didn't include the $10k just to get the PPL)
I still wish I could do it.
