Run starts at 7:45. Emulator used was BizHawk 2.2.1 with bsnes core.
This was meant to be just a test run, luckily I was recording. During the run, I was more worried about getting the largest planes whenever they're available to optimize slot usage (DC-8 first and 747 later on), tried to avoid competition the most I've could to avoid the comparisons being shown at the end of every turn, and tried to avoid other unnecessary menuing and cutscenes (when buying planes, visiting menus).
I've committed a considerable amount of menuing mistakes, and some decisions weren't optimal in practice, I think 10min can be saved with proper planning (regarding purchasing planes, slots negotiations, better route pricing), and wouldn't be surprised if sub-1h is possible. That said, I'm pretty happy with that as I wasn't expecing to get a time around 1:15.
