DAvid...usually routes can be changed due to storm. A few weeks ago, we were flying from Los Angeles back to Miami.....it was during that last storm.....and instead of going through the gulf...the route changed by staying on the southern coast...going across the state of florida...and coming down the east coast......it added an extra hour of flight time....but we avoided the storm by around 1000 miles or so. They won't fly through a storm...
