If FA system could dispatch an email when a FP is filed, activated, and when activated every 10 mins with progress strip, this would be a really cool feature.
Sort of analagous to: (for example) I’m on Alaska #597 departing at 10:00AM from SEA, and Alaska sends me an email saying my flight is on time. Lots of room for improvement even in their system, but would be really cool if we could do this in GA too.
Naturally, this would lead to a desire to track more than 5 planes. I would say that 10 would be much more flexible. Then, members could track friends/family, etc.
