I am making a application that using FlightAware for flight schedule information and I would like to make a function is about flight delay but I am facing some problems on implementation.
First, If I need to monitor a flight delay status change, am I need to use “Set Alert” in class 3 for notify the system and use “PushAlert” in class 2 for receive the push message? Am I describe correct? I can’t sure the meaning of “Set Alert” and “Push Alert”.
Second, Once I notified the system for monitor a flight, if this flight changed the status many times, what is the counting of charge? Is count 1 times fee or multi times fee? I am confuse on this part.
Thanks for your time everyone
