how to check on a flight
One way to check the status of a flight is by using http://textengine.info. They have a flight status lookup that works by text message. This is convenient for when you're on the go and not connected to wifi. Also, you don't have to log into the airline's website and do a status check. Very easy to use. You just text the word flight + flight number to the service, and in seconds it gives you the current status, gate number, and time for departure/arrival.
