You can raise as much money as you want, but the people who own the media in airports won't sell to you if that's what you intend to do.
You are correct. I thought so, but it did not hurt to check. I lost nothing and learned a lot.
Unfortunately, right away a red flag went up. The airport approves ALL advertisers creative in ALL our markets. There’s no way they would allow any sort of negative connotation against the TSA/FAA. Clear Channel does not have the power to approve creative.
