That's a good question.
There are some of the fees that are on passengers, the security fees and the excise taxes. I know that's really about spending, but those are some of the things that are impacting us.
From a policy perspective, I don't want to take away from any safety aspects, but I guess there are things that could be looked at there in terms of the continuing costs that will be put on airports if additional requirements are added on a policy basis.
