I am a new registered user of Flight aware. I tracked a flight from Denver to Sacramento that I had to meet on arrival. I was notified of the flight plan filing and departure. I was NOT notified of the delays or arrival even though I had configured all status changes to be sent to my email, text, and pushed to my WP7 phone. The updated changes showed up on the website but only some of the notifications were actually sent (and the ones that worked came through on all three methods as they all should have). As a result I have no confidence in this software. Is there an explanation for this? This looks like just what I was looking for in flight tracking software but it seems to be unreliable. Please help!!
