(CNN) - While the mystery and geography have led to easy comparisons between the disappearances of the AirAsia flight and Malaysia Airlines Flight 370, there are also some distinct differences.
For starters, the search area for Flight 370 was much deeper in the Indian Ocean. Compared to the more shallow, heavily-trafficked Java Sea.
And then there are the sizes of the search areas. For Flight 370, it was about the size of West Virginia. For AirAsia, at least right now, it's about the size of West Virginia and South Carolina combined. Of course it's early yet.
And then there are the circumstances under which both planes went down, like the weather. It was crystal clear for that Malaysian air flight, in stark contrast with the conditions during this AirAsia flight.
