Scheduled Flights

I don't understand why there is such a large gap (24+ hours) between BJA005's flights. It's last flight departed a few hours before I took the screenshot.

BTW, my 707-320 flights aren't making much profit at all even if it has a very profitable route. Is this because of the high fuel costs?

703s are very inefficient, I've experienced that too. Flights aren't scheduled though, you click fly route, and when you do that, it'll depart at the pre-specified departure time. That time may be in the next day, and, remember, it is in the time zone of where the plane is.
