Nope, no time compression used at all. However I often find myself reaching for that time compression button on the flight path between Gadner and London. Sometimes I go into Keflavik, then on into London.
My flights are planned to make the most use of the available fuel on board to fly direct GPS over long hauls instead of hitting a bunch of VOR's and doing alot of turns and twists that use up fuel, which in turn shortens the maximum distance the plane can fly. I forget which islands they were, but they were east of Austrailia, and I landed with about 70 lbs of fuel left when I touched down on the runway!

I saved each flight plan, from point to point, both departure and arrival. I would save the flight right after plotting the flight plan, starting at either the gates or general parking, get IFR clearance and taxi to the runway being used, fly the trip, land and either taxi to gates or parking, shut down all systems and then save the flight, labled as "arrived at such n such airport". Then do it all over again from that airport and plot another flight plan to the next location, saving the flight prior to getting IFR clearance and before taking off. Needless to say, my saved flights folder is quite full!
On one trip from Keflavik into Amsterdam, at about 37,000 ft, there was a very, very close call with a 747.
The 747 was heading towards the states, not sure where from, but that puppy was heading right for me approaching from the port side. No air traffic alert from ATC at all, I had to "DIVE!" so that it wouldnt smash into me! I wish I could have taken a screenshot of it, but I was in the middle of doing a dive and trying to keep things together while this 747 decided to fly right into my flight path!
Had I not been looking out the window in VC mode, I would not have seen this thing comming and there would have been a mid air collision! :o
I never thought that the AI would like to play chicken! But I suppose the 747 won cuz it did not veer from its course at all! But it managed to make me take a dive and make my passengers spill their recent in-flight dinner!
