I will note that our sense of the economic situation of the airlines is that it could be significantly problematic for them to provide refunds at this time. It's important to note, I think, that they have not really been obtaining any revenues for some period of time now.
Obviously, the immediate forward picture also does not look particularly great for airlines to increase revenues. To suddenly require paying out the refunds all at once, which would be in the billions of dollars, could have very significant economic consequences for airlines. It would obviously vary among the airlines...and given the amount of outstanding vouchers that they do have, but we do believe the economic consequences could be serious indeed.
