We were using a bespoke piece of software that kept things very simple and easy to track, but for various reasons we had to migrate. IMO BizFlight is needlessly complex for simple tasks (about 8+ clicks to send a handling request) and lacks the overview necessary to watch larger fleets. If you're quiet and have time on your hands waiting for things to happen it'll do, but if you've got lots of plates spinning it won't help. It doesn't work the way you work - you need to work the way it does - PM me if you want more info.
I'm open to ideas on software that will work.
