People have asked this question before and there are a multitude of different potential ways. Supposedly Lyft can sync or calendar and in some cases was being sync'd automatically, perhaps it knew from that?
The app might pull accelerometer data in a way that suggests you just landed or were on a plane? Could it be that the cell towers in that area are known to be based at the airport?
