What I can say on this is that we're working very hard and very diligently, analyzing all of the many stress points in the system, and we're consulting very closely with the operators in the system. We're doing it in such a way as to make sure we differentiate between the large airlines and the large airports, the small airlines and the small airports, and the remote regional communities that rely heavily, some of them exclusively, on the air mode as their link to the rest of the country.
We're making sure that the diversity in the system and the fact that there are extreme stresses playing out in different ways across the different parts of the system are fully understood.
