Airline Name Missing from Commercial Flight Box

I have noticed that some airlines are missing from the drop down box on the flight tracker. One of these is Worldwide Jet. All of their flight call signs start with WWI and then the flight number.

For example if you type WWI74 under the flight tail number box it will be displayed. This is for flight 74

Basicly, I would have to say the best way to go about this is to email Flight Aware and ask them if they can include that airline in there next cycle. Hope this helps!
