You think 50K is a premium? When again will you have the opportunity to fly solo? Right now, it's costing you 50K, which, last I checked, is less than 200K (50K x4).
To me, the fact that you haven't already switched calls into your question your sustained ability to run this site.
1) Flying solo (means don't have to bother wife and kids, nor having to pay for them);
2) Flying new LH F (which you have not done... comparing old to new is like comparing UA J to LH F)
3) FCT + Porsche
4) The "Hobby" is becoming less and less attractive. In a year or two, your 50K will be worth half that.
So you don't sleep another hour in a bed. In a year, let alone ten, will you remember the extra hour of sleep, UA J, and saving 50K, or will you remember the nose of the 748 in LH F with a Porsche to the plane after sipping some top-shelf whiskey?
That's what I thought.
