YVR-YYC-YYZ-JFK-HEL-VIE
Judgment error on my part; it seemed like a good idea at the time!
I left Vancouver on August 19th at 21:45 and arrived in Vienna on the 21st at 18:35 (9:35 Vancouver time). This included an 8 or 9 hour stopover in Toronto to visit family en route to Vienna as well as a very nice 8-hour stopover in Helsinki.
So that was about 35 hours and 10 minutes if it was actually as scheduled.
