@bworld1 Another update: After I changed all of my flights, I went back into the TG/Compiler folder to back up the file and I found that the only file that had updated it's modified date was schedules.dat, so I guess this is the one that needs to be backed up to protect yourself. If you find anything different, let me know. So, I also created 1 UAL flight with hourly instead of daily and it takes off from KCLE, I want to see how that works. United uses terminal C and that is what I want to see a couple more planes at, I'll set you know how that works. If it's hourly, does a plane just pop into a gate before it starts the flight?, don't know.
