When planning a flight of duration of more than 5 to 6 hours it becomes impossible to stay away from internet if you are into it like crazy. Some International Flights like Delta provide internet connection in some of their flights and most probably you will get to know this when you book tickets but if you need to know earlier, haswifi is a good tool.
This tool takes in the carrier and flight number to find if the flight has an Internet connection you want to use.And if you do get the WiFi then keep checking the status live and even tweet or post it on Facebook. ( Via Lifehacker )
