I'm not aware of any specific issues in there with respect to security that would give us cause to be concerned. I know we're very diligent about which countries we fly to and which countries we allow service to be extended to.
I had personal experience when we extended the right to Air Algeria to fly to Canada. We were very diligent, and I thought our government did a great job of working through all the issues associated with having a flight to that part of the world; they were quite sensitive.
So no, I'm not aware of any particular aviation security issues that have been an impediment.
