Sabinaboy,
Car engines have air filters, jet engines do not.
The issue isn't that jet engines will fail because of the ash, but they will wear out in 100's of hours instead of 10000's of hours. In an industry that makes single digit operating margins in good years it would be unsustainable.
You might want to go flying now because you fear bankruptsy, but flying now may well have the same effect.
Lets wait until we see the results of the test flights.
