The free Web application Flight Wait creates a simple graphical representation of flight delay statuses. Select your home airport and you’ll see green, yellow, or red lines to connected cities indicating the time you’ll be waiting.
If all lines are green, the wait is a maximum of 15 minutes. If the lines are yellow, your airport or area is reporting delays between approximately 16-59 minutes. A red line indicates a wait of an additional one to two hours, and if the line is black, you’re stuck for at least two hours.
