So to give an example of how this works. I had phone calls for 10am EDT so I block 5hrs+1hr for time change, cheap gas stop, and drive to office. This means an 0300 launch this morning. Via the airlines it is a 0600 launch and I don't have to pre-flight plus have WIFI (and I generally Uber to ORD versus drive myself to KDPA so that is 30 mins of sleep).
0200 when I spring from my slumber there is a hard frost and I park outside, no go till sunlight. I do emails, move afternoon calls to next day. Sit at home In Chicago and do 10am calls (9am Chicago time) can't leave at dawn when the frost is gone because it would cause me to miss calls I can't reschedule. Depart around 1130 EDT. 9000ft was he definite sweet spot by about 15kts over 7000. Scrap base of clouds with no sun -3C and a lousy heater. Wear emergency sweater and enjoy the light and 2 whacks of moderate chop and trace ice. Land just before 1700 for first evening call. Eat at 47N pizza place. Do 1800 conference call on way to hotel in car. At 1852 decide to get up at 0400 to do email instead of working tonight, celebrate with Pinot Noir.
15hr and change day and I am 4hrs behind in the week because I had to fly during the prime of my day. So I play catch up all week and hope that I can burn enough hours to get out by 1800 on Friday for the 5hr flight back. While you can be somewhat work productive at altitude/IFR/autopilot it isn't like sitting in 2B.
Had it not been for my NJ car being at 47N and the need to carry stuff back to IL it would have been an airline week. It is nice though smoking when you fly :-)
