We had this discussion about ash when the Icelandic volcano blew up.

The facts of the matter are that turbine blades and nozzle guide vanes are very very expensive and they have a finite life that can be seriously shortened if they have to operate in contaminated air.

Comments regarding momentary inconvenience, attendance at football games, etc. are misplaced when one understands that the aircraft operator may face a bill for many hundreds of thousands of dollars if they miscalculate ash concentrations.

Furthermore, blades and vanes do not grow on trees, nor can you pick up spare engines at Bunnings. An aircraft can be out of service for months if the donks get cooked - then the traveling public will really have something to complain about.
