You can get the cheapest airfare on the market right now, but it’s not easy to find.

That’s because the NFL is playing hardball in trying to protect itself from legal challenges to its policy of selling air tickets through a third-party agent.

For instance, the league recently tried to get an order blocking the third-parties AirTicketNetwork from using the names of NFL players and teams in its ads on television and radio, but a judge denied the motion, citing antitrust concerns.

And the NFL has also filed a lawsuit in federal court in Texas against a company that lets people use its online ticketing system to buy tickets, but the league is arguing that the company violates antitrust law by trying to make a profit off its players.
