Flighty is in a weird place because I'm a rare/leisure traveller and wow Flighty nowhere near reasonably priced for that market.
I used it in free mode when I was on iOS, but it would be ~£10 per trip for something that would improve my life less than a coffee at the airport.
In my opinion they need to aggressively cut costly features (like weather data), and if they have different international data feeds, perhaps do region locked pricing. I don't fly to the US much, so let me buy a Europe and Asia subscription and skip the US costs. Or vice-versa. It would have needed to be ~£10 a year at most.
I fly around 6x/yr but I still found it useful enough to get the lifetime plan. I suppose if I only flew once per year I wouldn't have gotten it, but I don't mind paying ~$10/flight (probably even lower by now, and who knows what it will drop to by the time Flighty stops working, hopefully more like ~$1/flight). A typical trip might cost in the range of ~thousands of dollars so $10 to reduce my stress levels when there is a delay is worth it in my book.
For example... if there's a delay and so because you found out sooner you can stay home an extra hour instead of sitting at the airport I would pay $10 for that.
What does it actually do? People seem to get very excited about it but my flight status is always either “on the plane” or “not on the plane”
