I've been a flight sim enthusiast since the 1980s. What has kept me interested has been the increasing realism that can be simulated in this hobby. In line with my desire for realistic experiences, I mostly enjoy flying real-world airline routes. I've typically taken the pdf timetable for the airline and planned trips. The pdf allowed me to look for flights that were realistic for a pilot: from the hub to a destination, find the flight that leaves on the same aircraft type about an hour later, etc. I used United Airlines timetables for years until they were discontinued, so I switched to simulate flying Delta routes. Now, Delta seems to have stopped publishing a timetable that I can use to plan my flights.
Any tips on how to create an approximation of real world pilot schedules? I've looked at Virtual Airlines, but their schedules generally don't seem to reflect real world schedules.
