It has always been an iPhone app for many years, only now they have exposed some information on the site (Probably for getting incoming links), so this is more interesting if you are already an existing user of the app.

You only really need to know when (departure/arrival time) and where (terminal/gate), no?

What else necessary info that’s missing?

I mean, still better than having to go to airports' official pages

Was going to say this. I'm getting real tired of sites trying to force me to download their spyware apps
