I am not clear what you are considering, can you be more specific, ie., which flight(s) you already have booked?

My recent experience of a flight scheduled during H. Irma was that before it hit my destination the airline allowed a one-time re-scheduling 'with no change in price'.

After Irma, perhaps because of the effect of the storm, they allowed it to be rescheduled again, also at no change in price.
