They have not updated the software in 20 years, nor do they intend to. I actually had a phone call with a technical support rep about this, and he seemed almost offended when I suggested something resembling a 2005 interface, much less anything nearer to 2020. So, do you like the following?

1. Seeing an "export to Palm Desktop Calendar" option.
2. Seeing a reminder that the Outlook calendar option "requires Outlook 98 or newer"
2. Having to sit at your Windows PC--and no other--to use the Windows-only-on-your-hard-drive software to submit open time alerts, or to use EasyBid or EasySwap (for those guys who use those products). No app, no web interface, no ability to use a Chromebook, iMac (unless running Windows or a Windows emulator), iPad, smart phone, you get the idea.

All that said, the open time alerts--amazingly--are a very useful feature that I have also found lucrative, like Sailing has. I just wish that Sabre (who bought FDS years ago for their Flica product which Delta doesn't use) would update the two decade old software, But as long as you accept that they won't, the open time alerts are still pretty nice.
