Booking Flight ERROR Company Policy (Policies) to hide flights: Air Fare greater than $1

[caseyc]

I need to book a flight and the preferred (only non-stop) flight, that I have taken twice before, is resulting in error/popup: 

Company policy is set to hide the flights you have chosen, so we cannot quote these flights:
American Airlines 1208 DFW-BUR
American Airlines 1208 BUR-DFW

Total Fare: USD 466.42

Policy (Policies) to hide flights:
Air Fare is greater than $1 

I need to get this flight booked very soon!

@caseyc I would recommend you call your travel agency. They can get the flight booked. They might even be able to tell you why you were getting an error. 

The rule in place seems a little odd to me. Why hide fares greater than $1? Is it only for American Airlines?
