Speaking as SLF, the airlines may decide to restart a limited flight schedule, do you really think that I would put my family or myself at risk, under the present conditions, just because you think it will be ok. The decision to fly must be a decision based on safety, not on economic necessity. If there was just one incident, that was attributed to volcanic ash, which the airline was aware of, the resultant fall out from the worlds press would be far more catastrophic. Having seen and read many comments and views from informed sources, I am left with the overall impression that we do not know enough about this situation to be able to safely operate aircraft. At the end of the day, you may be ready to operate the planes, it is up to us to get on them.
