Then you're doomed to frustration, because it is rational to alter your risk calculus to minimize stress. The cost to most people of altering their plans (eg choosing a different carrier when they fly) is less than the cost of anxiety or stress alleviation.
It's also rational to minimize stress by convincing yourself that the risk is actually low.
The dude asked for a rational perspective. I gave it. If you want to insist that people should avoid one of the safest activities in the history of civilization because it's rational to avoid fear, well, go for it, but you're not going to convince me.
Saying that it might be rational for someone to change their flight to a different carrier is a long way from 'insisting' that they don't fly. What a ridiculous straw man argument.
