There are basically a whole bunch of aircraft standing around that nobody can use. The problem for Airbus is that you cannot pluck feathers from a bald chicken (you cannot extract money from a near bankrupt airline) and no one else is looking for aircraft right now, so essentially there is no queue.
On a more positive note: Boeing is theoretically in a much worse state, as delays in the 737 Max (and the 787 and the 777X) means that airlines can cancel those orders without penalty. In practice this only makes a difference for the balance books, not for the cash flow.
