But flight time is fixed; anything happens in the sky will it effect on the duration of the journey?

No, the flight time is not fixed.  The flight distance is fixed, while the flight time varies because the speed varies.

Those who got 1 hour correctly computed the flight time in good weather, while those who got 1.5 hours correctly computed the flight time in bad weather.  The question asks for the latter, so the final answer is 1.5 hours.  Test it.
