> one of the most important pieces of data for a flight, its duration

Flighty is all about getting you to the airport in time for your flight, so the most important pieces of information are things like departure times, connection times, delay information, terminal and boarding gate. These are prioritised in the interface.

The flight duration is set when you book the flight and it's not going to change, there is no reason to prioritise this.

I think this would be useful but difficult data to get. Airlines sometimes will push boarding announcements to their own apps but I doubt they would agree to feed Flighty.

In my extensive travel experience, more than half the time the boarding time listed at the gate isn't even correct.

Boarding is hard because it's at the discretion of the airlines, yeah. Departure time is easier because of https://www.fly.faa.gov/edct/showEDCT
