One of the problems with bailouts is you end up bailing out the banks and bondholders. American tax dollars for the middle class will keep the payments coming to the people who least need it. We are in this together, we need to all pay for it, including banks and bondholders.
I don't know how to do that outside of bankruptcy. The problem is how to you put the whole airline industry through bankruptcy at the same time.
Maybe legalized forebearance for airport fees, aircraft payments, etc. Maybe that is better than tax dollars going through the airlines as pass thru entities to pay off the bondholders.
